"""
In 'temp.log', I get these two lines :
2018-08-10_19:47:46:107.400 - WARNING - py.warnings - warnings:99 :: UserWarning: Warning message !!!
2018-08-10_19:47:46:108.400 - WARNING - __main__ - bug_capture_warning:43 :: Logging message !!!

If we look at the first line of log, we see 'warnings:99'
but in my opinion it should be 'temp_code:42'
