MINGW64 doesn't print during execution

Question

I'm using Git Bash to run my Python scripts on Windows. I noticed that the console doesn't print while my scripts are running. All the strings are printed just when the scripts finish. I read that is a buffer and line break issue. How can I fix it?

Answer 1

I am using MINGW64 on Windows10, and python -u works for me. For example,

   python -u foo.py

From python --help:

-u     : unbuffered binary stdout and stderr; also PYTHONUNBUFFERED=x
         see man page for details on internal buffering relating to '-u'

Answer 2

I solve this including sys.stdout.flush() after each print().
