>>> "{a}.{b}.{c}".format(a = "aaa", b = "bbb", c = "ccc") ## 关键字参数 'aaa.bbb.ccc' >>> "{a}.{b}.{c}".format(a = "ccc", b = "bbb", c = "aaaa") 'ccc.bbb.aaaa' >>> "\t{a}.{b}.{c}".format(a = "ccc", b = "bbb", c = "aaaa") '\tccc.bbb.aaaa' >>> print("\t{a}.{b}.{c}".format(a = "ccc", b = "bbb", c = "aaaa")) ccc.bbb.aaaa
当同时出现位置参数和关键字参数时, 位置参数应写在关键字参数的前面。
