Hello Sir i write the code as per the instruction but shows error.
import json
import boto3
client = boto3.client('ec2')
def lambda_handler(event, context):
response = client.describe_instances(
Filters=[
{
'Name': 'tag:weekend',
'values': [
'9-22',
]
},
],
)
instances = []
length = len(response['Reservations'])
for i in range(length):
instanceID = response['Reservations'][i]['instances'][0]['instanceId']
instances.append(instanceID)
if not instances:
print("No instance found")
else:
response = client.stop_instances(
InstanceIDs=instances,
)
Error :

"errorMessage": "Syntax error in module 'lambda_function': unindent does not match any outer indentation level (lambda_function.py, line 26)",

]
}

There's an indentation error for your if/else block. You shouldn't have space in front if/else statements. I would suggest selecting the code below and hit shift+tab.
if not instances:
print("No instance found")
else:
response = client.stop_instances(
InstanceIDs=instances,
)
Hope this helps.

looks like you may have modified function name?
