I want to take input from a file(input.txt) into my .py file and display it in an output file(output.txt). I don't want to use file handling at all.

I tried following in terminal:

$ python3 hello.py > output.txt

and a file was created with the output.

But is there a method such that I can take input from a file to the .py file and it generates output.txt.

something like:

$ input.txt > python3 hello.py > output.txt

  • @Aaron duplicates shouldn't be deleted, they should be linked to a dupe, dupes aren't bad they're different ways of expressing the problem that others might find Commented Jun 26, 2017 at 12:53
