Python datetime.strftime() delegates to C strftime() function that is platform-dependent:
The full set of format codes supported varies across platforms, because Python calls the platform C library’s strftime() function, and platform variations are common. To see the full set of format codes supported on your platform, consult the strftime(3) documentation.
- (dash) Do not pad a numeric result string.
The result on my Ubuntu machine:
>>> from datetime import datetime>>> datetime.now().strftime('%d')'07'>>> datetime.now().strftime('%-d')'7'
