The string is never 452 truncated. If specified the fillchar is used instead of spaces. 453 454 """ 455 return s.center(width, *args) 456 457 # Zero-fill a number, e.g., (12, 3) --> '012' and (-3, 3) --> '-03' 458 # Decadent feature: the argument may be a string ...
("ww",20) 'ww ' >>> string.rjust('ww',20) ' ww' >>> string.center('ww',20) ' ww ' string.zfill(s, width) Pad a numeric string on the left with zero digits until the given width is reached. Strings starting with a sign are handled correctly. >>> string.zfill('ww',20)...
The Zero Flag (0) When a formatted numeric value is shorter than the specified field width, the default behavior is to pad the field with ASCII space characters to the left of the value. The 0 flag causes padding with "0" characters instead: Python >>> "%05d" % 123 '00123' >>> ...
