Why when import pygame, it prints the version and welcome message. How delete it?

It works for me:

import osos.environ['PYGAME_HIDE_SUPPORT_PROMPT'] = "hide"import pygame

I didn't see a natural way to do it (yours is the only Google result for this that I could find), but I did achieve the same thing by temporarily disabling stdout while importing pygame.

import os, syswith open(os.devnull, 'w') as f:    # disable stdout    oldstdout = sys.stdout    sys.stdout = f    import pygame    # enable stdout    sys.stdout = oldstdout

Here's the alternative suggested by @Mad Physicist:

import contextlibwith contextlib.redirect_stdout(None):    import pygame

The source code contains a condition guarding the printing of this message:

if 'PYGAME_HIDE_SUPPORT_PROMPT' not in os.environ:    print('pygame %s' % ver)    print('Hello from the pygame community. https://www.pygame.org/contribute.html')

See this commit

This was added fairly recently (October 2018) and so far 1.9.4 was released prior to this. Once the next version > 1.9.4 is released you should simply by able to run your code with PYGAME_HIDE_SUPPORT_PROMPT= ./my_code.py to hide the message.
