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.
The Python docs contain all the format codes that the C standard (1989 version) requires, and these work on all platforms with a standard C implementation. Note that the 1999 version of the C standard added additional format codes. These include codes for non-zero-padded numbers, that can be obtained by appending a dash (-) (UNIX) or hash (#) (Windows) after the percent (%) sign.
