python - Check if programm runs in Debug mode -

i use pycharm ide python programming.

is there possibility check, whether i'm in debugging mode or not when run proframm?

i use pyplot plt , want figure shown if debug programm. yes, have global boolean debug set myself, sexier solution.

thank support!

according documentation, settrace / gettrace functions used in order implement python debugger:

sys.settrace(tracefunc)  

set system’s trace function, allows implement python source code debugger in python. function thread-specific; debugger support multiple threads, must registered using settrace() each thread being debugged.

however, these methods may not available in implementations:

cpython implementation detail: settrace() function intended implementing debuggers, profilers, coverage tools , like. behavior part of implementation platform, rather part of language definition, , may not available in python implementations.

you use following snippet in order check if debugging code:

import sys   gettrace = getattr(sys, 'gettrace', none)  if gettrace none:     print('no sys.gettrace') elif gettrace():     print('hmm, big debugger watching me') else:     print("let's interesting")     print(1 / 0) 

this 1 works pdb:

$ python -m pdb main.py  > /home/soon/src/python/main/main.py(3)<module>() -> import sys (pdb) step > /home/soon/src/python/main/main.py(6)<module>() -> gettrace = getattr(sys, 'gettrace', none) (pdb) step > /home/soon/src/python/main/main.py(8)<module>() -> if gettrace none: (pdb) step > /home/soon/src/python/main/main.py(10)<module>() -> elif gettrace(): (pdb) step > /home/soon/src/python/main/main.py(11)<module>() -> print('hmm, big debugger watching me') (pdb) step hmm, big debugger watching me --return-- > /home/soon/src/python/main/main.py(11)<module>()->none -> print('hmm, big debugger watching me') 

and pycharm:

/usr/bin/python3 /opt/pycharm-professional/helpers/pydev/pydevd.py --multiproc --qt-support --client 127.0.0.1 --port 34192 --file /home/soon/src/python/main/main.py pydev debugger: process 17250 connecting  connected pydev debugger (build 143.1559) hmm, big debugger watching me  process finished exit code 0
