The accepted answer got me on the right track, however in my case, a shell script that Jenkins was running was capturing the output of the python script in a subshell to a variable i.e. a=$(python_script), so it was not being echoed....

To solve the problem I just had to log to stderr instead of stdout, i.e.

import sys
sys.stderr.write("my info\n")
sys.stdout.flush()

Try using -u (unbuffered) option when running the python script.

python -u my_script.py

I believe that what you need to do is a flush, try:

import sys
sys.stdout.flush()

It should help.

Any output to stdout from a process spawned by Jenkins should be captured by Console Output. One caveat is that it won't be displayed until a newline character is printed, so make sure your lines are terminated.

If you are launching python in some weird way that dis-associates it from Jenkins parent process, then I can't help you.
