When i download i want the season and episode have a leading zero instead of only a single number. I use the template s%(season_number)se%(episode_number)s and i can't find anything that will make it use two numbers 01, 02, 03 and i don't want to add it manually because that will make it hard to check for every download if there should be a leading 0 or not.
I'm new to youtube-dl so maybe i have missed something?

Read FAQ?

The special sequences may be formatted according to python string formatting operations. For example, %(NAME)s or %(NAME)05d

I have no idea how that works, but thanks for your help @dstftw...

S%(season_number)05d vs. S%(season_number)s for example...

Thanks, I don't have to rename my files anymore after download.
-o '%(series)s - S0%(season_number)sE0%(episode_number)s - %(title)s.%(ext)s"
With above I was getting S0E01,SE02 (OK) but S01E010, S01E011 (NOK)
'%(series)s - S%(season_number)**02d**E%(episode_number)**02d** - %(episode)s.%(ext)s'
I get "ShowName - S01E01 - BlaBlaBla.mp4"

also tried 03d,04d

Tested:

>>> print '%(language)s has %(number)02d quote types.' % \
... {"language": "Python", "number": 2}
Python has 02 quote types.

>>> print '%(language)s has %(number)03d quote types.' % \
... {"language": "Python", "number": 2}
Python has 002 quote types.

>>> print '%(language)s has %(number)05d quote types.' % \
... {"language": "Python", "number": 2}
Python has 00002 quote types.
