sir because of this course i have learnt many things...thank you for bringing this course for free ...... middle class families are successfull because of you
Guys he is trying his best to teach us all the topics in a very different so we can learn all the complex and advance topics in a very easy manner, and in return all he asks just some comments, and we are not completing the goal. That's not fair, we should keep motivating him for his efforts.
for 7th problem, implemented the following solution: userIn = int(input("Enter a number: ")) while userIn not in range(1,11): print("Number out of range!") userIn = int(input("Enter a number: "))
Problem 3: table = int(input("Enter the table: ")) table_print = 1 for i in range(1, 10+1): if i == 5: continue table_print = table * i print(table, "*" ,i, "=", table_print)
Q4. Reverse string using Loop a = "Gulab Alam" b = len(a)-1 while b >= 0: print(a[b]) b-=1 Using FOR Loop x = "Tarun" y = " " for i in x: y = i + y print(y)
10:15 Sir it's wrong... Correct Answer : 30 Correct Code : n=10 sum_even=0 for i in range(1,n+1): if(i%2==0): sum_even += i print("Sum of even numbers are :",sum_even)
For those who want to protect original number in factorial problem, create another value x then. x = number and then start loop and decrease x. Since x = x-1 will assign a new value to x, the value of number remains unaffected. But if you are still doubtful, just do x = int(number). This is initially create 2 values in memory.
Generally while loop seems difficult to me, here is the answer to those who are trying using while loop:☺ Problem 1: # while list = [8, 5, -5 , -9, -7] n = 0 ij = 0 while n < len(list): if list[n] > 0: ij +=1 n +=1 print(ij) Problem 2 : # using while n = 0 s = 0 while n
# Sum of Even Numbers # Problem: Calculate the sum of even numbers up to a given number n. n = int(input("Enter the number: ")) sum_of_even = 0 for item in range(1, n + 1): if item % 2 == 0: sum_of_even += item # Add the even number to sum_of_even print(sum_of_even)
Solution 2:- n = int(input("Enter a number: ")) sum_even = 0 for i in range(0, n, 2): sum_even += i print("The sum of all even numbers up to", n, "is", sum_even)
10:17 : ac my understanding . sum of even number do not mean number of even number??? and formula for sum of consecutive even numver upto nth number is n^2 or sum+=i
# Problem: Print the multiplication table for a given number up to 10, but skip the fifth iteration. n = int(input("Enter a number: ")) for i in range(1,11): if(i==5): continue print("{} * {} = {}".format(n,i,(n*i)))
Even Number Question Solution . starting_range = int(input("Enter the number here: ")) ending_range = int(input("Enter the number here: ")) sum_even_num = 0 for num in range(starting_range,ending_range): if num%2==0: sum_even_num = sum_even_num + num print(sum_even_num)
# Problem: Calculate the sum of even numbers up to a given number n. number : int = int(input("Enter a number up to which you want to calclate sum of even numbers")) sum_of_even_numbers:int = 0 for i in range(1,number+1): if i%2 == 0: sum_of_even_numbers = sum_of_even_numbers+ i print(sum_of_even_numbers)
10:10 Sir in the question it is given to print the sum of even numbers. But you have calculated the total number of even numbers in range(1, n+1). Correct code should be: n = 10 sum = 0 for number in range(1, n+1): if number%2 == 0: sum += number print("Sum of even numbers: ",sum)
Multiplication Table Printer (upto 10, but skip 5th iteration) Using For Loop n = int(input("Enter the number: ")) for i in range (1,11): if i == 5: continue print(n,"*",i,"=",n*i) Using While Loop i = 1 num = 7 while i
Abdul Wahid from Bangladesh ------------------------------------05 number = 5 factorial = 1 while number > 0: factorial = factorial * number number = number - 1 print("factorial number value is : ", factorial)
[Sir ,a little Correction Q_2] # number = int(input("Enter the number till you want to get sum :")) sum = 0 number = 10 for i in range(number): # if i % 2 == 0: sum = sum+i print(sum)
Count Positive Number Using While Loop num = [1, -2, 3, -4, 5, 6, -7, -8, 9, 10] i = 0 postive_num = 0 while i < len(num): if num[i] > 0: postive_num+=1 i+=1 print("Final Count:",postive_num) Using For Loop num = [1, -2, 3, -4, 5, 6, -7, -8, 9, 10] postive_num1 = 0 for i in num: if i > 0: postive_num1+=1 print("Count of Positive Number:", postive_num1) Using List Comprehensive p= [i for i in num if i > 0] print("Positive Number in List:",len(p))
Solution of the 2nd Problem: num=int(input("Enter the number here")) sum_even_num=0 for i in range(num+1): if i%2==0: sum_even_num=sum_even_num+i print("Sum of even nos. is", sum_even_num)
one more way to create the third solution: num = int(input("enter you table number: ")) for i in range(1,11): if i != 5: print(num, "X", i, "=", num*i )
Q2. Sum of Even Number Using For Loop(way-1) n = int(input("Enter the value of n:")) sum_1= 0 for i in range (0,n+1,2): sum_1+=i print("Sum of Even Number:", sum_1) Using For Loop(way-2) num = int(input("Enter the value of num:")) sum_positive_num=0 for i in range(0,num+1): if i%2==0: sum_positive_num+=i print("Sum of Even Num:", sum_positive_num) Using While Loop number = int(input("Enter Number:")) count_of_even = 0 i=0 while i < number+1: if i%2==0: count_of_even+=i i+=1 print("Sum of even number:",count_of_even)
I think "f" string is more good then that like we do in javascript ``` number = 3 for i in range(1, 11): if i == 5: print(""" "5" is Detected""") continue print(f"{number} x {i}= {number * i}") ```
For Problem 2, Question is asking to sum all even numbers, Not just count. The correct solution is anyone is wondering is : - def sum_checker(n): even_list = [] for i in range(1,n+1): if i%2 == 0: even_list.append(i) final_sum = sum(even_list) return final_sum
It is very disheartening to see that very few people are following this amazing playlist. The habit of consuming content has made our mindset so fragile that we could scroll shorts for infinity but we can't sit back straight for an hour to solve basic problems. And then people will whine about AI taking over us on the internet. If we do not change this way of living then maybe the AI doom is inevitable. But if we start learning and developing a problem-solving mindset rather than watching endless tutorials then we could really grow professionally and personally. This playlist, and almost every other playlist made by Hitesh sir really beats any paid tutorials since this series develops a problem-solving mindset rather than making people syntax ninja.
For those who didn't understand the " reverse string code " : input_string = "Python" reverse_string = "" for char in input_string : # reverse_string = reverse_string + char reverse_string = char + reverse_string print(reverse_string) Explaination:- Iteration 1 (char = 'P'): At the beginning, reverse_string is an empty string. After the first iteration, reverse_string becomes 'P'. Iteration 2 (char = 'y'): reverse_string is currently 'P'. Concatenating 'y' with 'P', so reverse_string becomes 'yP'. Iteration 3 (char = 't'): reverse_string is currently 'yP'. Concatenating 't' with 'yP', so reverse_string becomes 'tyP'. Iteration 4 (char = 'h'): reverse_string is currently 'tyP'. Concatenating 'h' with 'tyP', so reverse_string becomes 'htyP'. Iteration 5 (char = 'o'): reverse_string is currently 'htyP'. Concatenating 'o' with 'htyP', so reverse_string becomes 'ohtyP'. Iteration 6 (char = 'n'): reverse_string is currently 'ohtyP'. Concatenating 'n' with 'ohtyP', so reverse_string becomes 'nohtyP'. After the loop completes, reverse_string contains the reversed version of the input string 'Python', which is 'nohtyP'.
i have 2 years of experience in Python but still watch your video to get the internal working of each topic.🫡 After watching your video i have started to assign the value by giving space. before=2 after = 2 😅😅

attempts = 1
password = "password"
while True:
user_input = input("Enter password: ")
if attempts < max_tries:
if user_input == password:
print("logged in succesfully")
break
else:

sir i think in 2nd problem the question would be count the even no. upto n (sum means 2+4+6+8+10)
n = 10
even = 0
for i in range(1,n+1):
if i % 2 == 0:
even += i
print(even)
that's why I thought. It should have been (sum means 2+4+6+8+10). Maybe he meant counting total number of even numbers up to 10.
@@SamraatMaharjan yes, i also came for this. it is mentioned sum of even numbers not count of even numbers

Sir love the way you explain the complex concepts easily in a simple way Hats off to you❤❤
For those who want to protect original number in factorial problem, create another value x then.
x = number and then start loop and decrease x. Since x = x-1 will assign a new value to x, the value of number remains unaffected.
But if you are still doubtful, just do x = int(number). This is initially create 2 values in memory.
#Validate Input

Generally while loop seems difficult to me, here is the answer to those who are trying using while loop:☺
Problem 1:
# while
list = [8, 5, -5 , -9, -7]
n = 0
ij = 0
while n < len(list):
if list[n] > 0:
ij +=1
n +=1
print(ij)
Problem 2 :
# using while
n = 0
s = 0
while n
number = 10
sum = 0
for i in range(1,number+1):
if i % 2 == 0:
sum += i
print(sum)
Ans is : 30
bro sum is a method ap variable ka name change kro

10:10 Sir in the question it is given to print the sum of even numbers. But you have calculated the total number of even numbers in range(1, n+1). Correct code should be:
n = 10
sum = 0
for number in range(1, n+1):
if number%2 == 0:
sum += number
print("Sum of even numbers: ",sum)
number = 15
sum = 0
for num in range(0, number+1):
if num % 2 == 0:
sum = sum + num
print("Total sum is ", sum)

i=1
while i
10:12 on line 6, 1 should be replaced with ‘i’ then we get the some of even numbers.
Thank you❤❤❤

#string reverse using while loop
university_name = 'Riphah International University'
string_length = len(university_name)-1
while(string_length>=0):
print(university_name[string_length] , end=' ')
string_length = string_length-1
Solution of the 2nd Problem:
num=int(input("Enter the number here"))
sum_even_num=0
for i in range(num+1):
if i%2==0:
sum_even_num=sum_even_num+i
print("Sum of even nos. is", sum_even_num)
numbers=[1,-2,3,-4,5,6,-7,-8,9,10]
n=len(numbers)
count=0
for i in range(n):
if numbers[i]>0:
count=count+1
print(count)
17:53 string is immutable
one more way to create the third solution:
num = int(input("enter you table number: "))
for i in range(1,11):
if i != 5:
print(num, "X", i, "=", num*i )
Question: 7-
while True:
number=int(input("please enter the number between 1 and 10 :"))
if 1
#Factorial Using While Loop
n = int(input("Enter Number which to be factorial: ")) i=1
while_fact = 1
while i
Q2. Sum of Even Number
Using For Loop(way-1)
n = int(input("Enter the value of n:"))
sum_1= 0
for i in range (0,n+1,2):
sum_1+=i
print("Sum of Even Number:", sum_1)
Using For Loop(way-2)
num = int(input("Enter the value of num:"))
sum_positive_num=0
for i in range(0,num+1):
if i%2==0:
sum_positive_num+=i
print("Sum of Even Num:", sum_positive_num)
Using While Loop
number = int(input("Enter Number:"))
count_of_even = 0
i=0
while i < number+1:
if i%2==0:
count_of_even+=i
i+=1
print("Sum of even number:",count_of_even)
for #2 problem --> sum_even += i #30
for #4 problem another way could be --> for char in name:
rev_string = rev_string.join(char) + rev_string
distance = int(input("Enter Distace of your location : "))
if distance 3 and distance 15:
mode = "Car"
print(mode)
thank you so much, sir.
really enjoy course
number = 5
factorial = 1
while number > 0:
factorial *= number
number = number - 1
print("factorial number value is : ", factorial)

Consistently watching and practicing every topic simultaneously
I think "f" string is more good then that like we do in javascript
```
number = 3
for i in range(1, 11):
if i == 5:
print(""" "5" is Detected""")
continue
print(f"{number} x {i}= {number * i}")
```
For Problem 2, Question is asking to sum all even numbers, Not just count. The correct solution is anyone is wondering is : -
def sum_checker(n):
even_list = []
for i in range(1,n+1):
if i%2 == 0:
even_list.append(i)
final_sum = sum(even_list)
return final_sum
Nope. Aapne question hamesha isi trh dekha h, isliye yahi sahi solution lagta h.
Kuch different h ye
@@chaiaurcode Sir, you did Counting of even Number i guess ?
It is very disheartening to see that very few people are following this amazing playlist. The habit of consuming content has made our mindset so fragile that we could scroll shorts for infinity but we can't sit back straight for an hour to solve basic problems. And then people will whine about AI taking over us on the internet. If we do not change this way of living then maybe the AI doom is inevitable. But if we start learning and developing a problem-solving mindset rather than watching endless tutorials then we could really grow professionally and personally. This playlist, and almost every other playlist made by Hitesh sir really beats any paid tutorials since this series develops a problem-solving mindset rather than making people syntax ninja.

Sum of even :-
n=10
even_sum=0
for i in range(1,n+1):
If (i%2==0):
even_sum+=i
print(even_sum)
For those who didn't understand the " reverse string code " :
input_string = "Python"
reverse_string = ""
for char in input_string :
# reverse_string = reverse_string + char
reverse_string = char + reverse_string
print(reverse_string)
Explaination:- Iteration 1 (char = 'P'):
At the beginning, reverse_string is an empty string.
After the first iteration, reverse_string becomes 'P'.
Iteration 2 (char = 'y'):
reverse_string is currently 'P'.
Concatenating 'y' with 'P', so reverse_string becomes 'yP'.
Iteration 3 (char = 't'):
reverse_string is currently 'yP'.
Concatenating 't' with 'yP', so reverse_string becomes 'tyP'.
Iteration 4 (char = 'h'):
reverse_string is currently 'tyP'.
Concatenating 'h' with 'tyP', so reverse_string becomes 'htyP'.
Iteration 5 (char = 'o'):
reverse_string is currently 'htyP'.
Concatenating 'o' with 'htyP', so reverse_string becomes 'ohtyP'.
Iteration 6 (char = 'n'):
reverse_string is currently 'ohtyP'.
Concatenating 'n' with 'ohtyP', so reverse_string becomes 'nohtyP'.
After the loop completes, reverse_string contains the reversed version of the input string 'Python', which is 'nohtyP'.
i have 2 years of experience in Python but still watch your video to get the internal working of each topic.🫡
After watching your video i have started to assign the value by giving space.
before=2
after = 2
