If you're using Linux or Windows PowerShell you could pipe " | " it after using cat on input.txt file, suppose you have input.txt file and your code.py file in same directory you could use:

cat input.txt | python code.py

This will provide python input from STDIN. for example: if for example you're trying get names from input.txt file

input.txt has

code.py has

print(" is not ".join(input().rstrip().split(',')))

would give

john is not matthew is not peter is not albert
