Can't run python script with an txt entry in powershell [Errno 22]

Question

I have installed python 3.7, I'm really new to this and read you can run a script with a txt entry in PowerShell (already did environment path configs). I opened PowerShell and type: - cd [Python script directory] - python main_1.py

It should run but gives an error in return, here is the error . Any help will be appreciated.

Answer 1

Input redirection (the command line operator < ) is not implemented in Windows Powershell . You may want to switch to cmd.exe if you need this functionality.

Answer 2

You must either use a full path

open(r"C:\description_files\program_description.txt","r")

Or a relative path

open("program_description.txt","r")
