A complex nested loop example in python
Bro you had it already installed if you want to show a tutorial at least delete the application and redo it plus that was very fast I did not like that at least try and do the video tutorial step by step I bet you he does that to all his videos...
Hey there. A system analyst here
This video is useless because he had already installed the program on his machine, we came here because our installation does not give us the anaconda icon after that "installation failed" text.
So in reality this is just being a project manager
Great efforts. Pl keep it up
Thank you for this video. It gives a better explanation than what my textbook does lol.
Thank you so mush
This is helpful thank you so much
Thanks for making this video. It seems strange that wouldn’t keep an Order ID or an Order Date, but this is an exercise.
Very helpful tutorial. now need to see this implemented.
Very helpful
thankz
okay so the anaconda was obviously already installed in your computer. but what do you do when you're installing for the first time and it says "installation failed"?
yeah, rushed video. If your going to post a tutorial, post a tutorial with every step
Hey I’m facing the same issue , how did u resolve it??
@@nooooooor9678 having the same issue is there a solution

Muchas gracias, me ha servido
Thank you
Thank you Isaac! You totally nailed it.
can you help please, i work as a system analyst in top 1 bank in russia and would like to move to the usa. But I ran into a problem: with us, the main tasks of a system analyst include API design and description of the specification, description of functional and non-functional requirements for the system. Which specialist solves these problems in the USA? Are such specialists in demand?
Thank you sir
After lot of searching I got this vidieo. really helpful
This is a strange field. I think employers are confused when hiring for analysts. A lot of job postings for systems analysts are basically just programming jobs. Most of the job postings don't even include analyst duties but rather just programming duties. Not sure why then do they just not open the positions as programmers or developers. I went to school and studied Computer Information Systems and studied systems analysis and design but very minimal programming so how could I be an analyst if I don't have that much programming knowlege?
So true! This is why here I focused on system analyst (in a traditional sense). However, tech fields undergo changes over time, and now everything is centered around data science. Consequently, being a system analyst also involves skills like programming and data analysis. Nevertheless, there is still a significant demand for genuine system analysts.
Sorry, but if you dont like programming you just shouldnt get into IT ...
@@tustak In case you just woke from under a rock, a whole section of IT has absolutely nothing to do with programming. I use to work for a company where a programmer didn't know how to install Windows on a computer. Plus, I mentioned nothing about not liking programming. The argument is that what is advertised as this career in College/Universities/Technical Schools is not what the actual job is in real life. Not sure why this simple argument is hard to understand.
@@yiaxiong7864do you think that programmer was a good example of someone who should get employed? I think your reference speak for itself.
@@tustak I'm sure he was excellent at HIS job, programming. IT is a large field. If you think you are required to know all the areas of IT because you havea a role in the field, you've been lied to.
Thank you
Finally something which works. Thanks a lot.
TRASH EXAMPLE, TIME WASTING!!!!
Thank you Professor!

Say, How do I split my screen vertically like yours?
Once you view your dataset click on query and then click on "in split tab"
@@isaacv4433 thanks,
Great insight to understanding requirements! Thanks
Albeit a little hard to hear, you helped me solve my problem of not being able to load large data csv files into SQL. Hats off to you sir. Thank you and the like is yours.
Glad you find this helpful Rabdul.
Is Solutions Analyst same as System Analyst / Business Analyst?
Srikanth solution analyst does a little bit of both business and system analyses jobs. But to b honest with you, it is expected from system analysts to know a bit about business analysts jobs and vice versa. These definitions getting blurry in newer positions.
