2019-12-08 20:56:07AVicennAsetname: Hello, I use decorators in my Python project. I tested project with cProfile(profiling). Then, I decide did test with some decorator code fragments. Some results were surprising: import functools import cProfile def decor(func): @functools.wraps(func) def wraps(*args, **kwargs): return func(*args, **kwargs) return wraps @decor def count(g_val): if g_val < 1: print("End") else: count(g_val - 1) cProfile.run('count(102)') OS names: Windows, Linux - x64 Python versions: 3.6.8, 3.4.3 - x64 # cProfile using into the .py file python dec_profile.py End 210 function calls (6 primitive calls) in 0.000 seconds Ordered by: standard name ncalls tottime percall cumtime percall filename:lineno(function) 1 0.000 0.000 0.000 0.000 <string>:1(<module>) 103/1 0.000 0.000 0.000 0.000 timeer.py:10(count) 103/1 0.000 0.000 0.000 0.000 timeer.py:5(wraps) 1 0.000 0.000 0.000 0.000 {built-in method builtins.exec} 1 0.000 0.000 0.000 0.000 {built-in method builtins.print} 1 0.000 0.000 0.000 0.000 {method 'disable' of '_lsprof.Profiler' objects} # Instead of 102 used ---> 82, 22, 33, 72 and etc. also gave me strange results like in 102.

2019-12-08 20:54:38AVicennAsetname: cProfiling.txt -> Hello, I use decorators in my Python project. I tested project with cProfile(profiling). Then, I decide did test with some decorator code fragments.
