Redirect file stdin in PyCharm

README.md

Introduction

For Pycharm IDE, we want to use redirect input file while running the code.

How to Use

1. You can make a file for a input data as like *.in.
2. Typing auto_redirect_input_file.py in top of code.
3. Click the "Edit Configuration".
4. Put the file name *.in in "Script parameters".
5. And, no and. Enjoy it!!

Talk is cheap. Show me the code.

import io
import sys

# Simulate the redirect stdin.
if len(sys.argv) > 1:
    filename = sys.argv[1]
    inp = ''.join(open(filename, "r").readlines())
    sys.stdin = io.StringIO(inp)
