TimedRotatingFileHandler(filename, when='W', interval=0, backupCount=0)
Produces:
ValueError: Unable to configure handler 'fichierSemaineStandard': You must specify a day for weekly rollover from 0 to 6 (0 is Monday): W
But the python documentation tells
value: 'W', type of interval: Week day (0=Monday)
So what's wrong?
