更改列表中元素的顺序

Question

如何更改列表中的名称顺序，以便名字在姓氏之前？这是我的样本列表：

names = ['Snow, John', 'Stark, Ariya', 'Baratheon, Myrcella']

Answer 1

试试这个

>>> [', '.join(reversed(name.split(', '))) for name in names]  
['John, Snow', 'Ariya, Stark', 'Myrcella, Baratheon']

Answer 2

split ", "名称，交换名字和姓氏，join按" "分隔。你可以在（嵌套）列表理解中完成所有这些：

>>> [" ".join([first, last]) for last, first in (name.split(", ") for name in names)]
['John Snow', 'Ariya Stark', 'Myrcella Baratheon']

或更短，使用reversed来反转名字和姓氏：

>>> [" ".join(reversed(name.split(", "))) for name in names]
['John Snow', 'Ariya Stark', 'Myrcella Baratheon']
