Avoid third party functions to wrote my python code into system debug-log?

[mark]

If anything means for you guys: I have already tried to redirect print which i want to hide from stdout to file or string buffer, but it seems nothing works. Solution form here doesn't work.

For example:

from cStringIO import StringIO # Python3 use: from io import StringIO
import sys
def startStream(myUrl):
    old_stdout = sys.stdout
    sys.stdout = mystdout = StringIO()
    from SomeFolder.SomeApp.SomeFile import PlayStream
    PlayStream(myUrl)
    

An again in system debug-log:

Output:
