要先附加的词

Question

如何在(First)

打印my_list后首先附加my_list = ['Hey','Lol (First)','Dasd','Go (First)','Asd'] for x in my_list: print(x) 的字词

如果相反，没有（第一个）的单词将首先附加。

Answer 1

使用列表理解：

>>> my_list = ['Hey','Lol (First)','Dasd','Go (First)','Asd']
>>> [x for x in my_list if 'First' in x] + [x for x in my_list if 'First' not in x]
['Lol (First)', 'Go (First)', 'Hey', 'Dasd', 'Asd']
>>> [x for x in my_list if 'First' not in x] + [x for x in my_list if 'First' in x]
['Hey', 'Dasd', 'Asd', 'Lol (First)', 'Go (First)']

>>> for x in [x for x in my_list if 'First' in x] + [x for x in my_list if 'First' not in x]:
...     print(x)

>>> for x in [x for x in my_list if 'First' not in x] + [x for x in my_list if 'First' in x]:
