python实现指定字符串补全空格的方法

本文实例讲述了python实现指定字符串补全空格的方法。分享给大家供大家参考。具体分析如下：

如果希望字符串的长度固定，给定的字符串又不够长度，我们可以通过rjust，ljust和center三个方法来给字符串补全空格

rjust，向右对其，在左边补空格

s = "123".rjust(5)
assert s == " 123"

ljust，向左对其，在右边补空格

s = "123".ljust(5)
assert s == "123 "

center，让字符串居中，在左右补空格

s = "123".center(5)
assert s == " 123 "

希望本文所述对大家的Python程序设计有所帮助。
