@getitneha, could you [upload your code to GitHub](https://docs.codecrafters.io/features/publish-to-github) and share the link? It will be much easier to debug if I can run it directly.

this is the code i used to run on my shell prompt  
git add .  
git commit --allow-empty -m “[any message]”  
git push origin master

and my python code is  
import sys

def main():  
sys.stdout.write(“$ “)  
# Simulate input for testing purposes (this would be replaced by actual input in the Codecrafters environment)  
command = input().strip() # Strip any extra spaces or newlines  
if command:  
print(f”{command}: command not found”)  
else:  
print(“No command entered”)

if **name** == “ **main** ”:  
main()
