When you have a function that insists on printing something, but you don't want it to print anything, do this...

force_do_not_print.py

## Based on https://stackoverflow.com/a/46129367/2383070

import os
import contextlib
 
def test_print(a):
    print(f'2 * {a} =')
    return 2*a
 
# Do not print the print statement in the function:
with open(os.devnull, "w") as f, contextlib.redirect_stdout(f):
    result = test_print(4)
 
print(result)
print()
 
# This is the raw function, and it does print the function statements
result = test_print(4)
print(result)

First call to function prints just 8 (becuase it is called after the "with" block).
Second call to function prints statements from the function and 8.
