python - 如果项目不以给定模式结尾则打印项目

Question

我有一个 list :

mylist = ['summer_C','summer_C1','summer_P','summer_C123','summer_p32']

我想打印所有不以以下模式结尾的项目:

'_C' or '_C%' (int) 

所以它可能是“_C”或“_C1”或“_C2939”之类的内容

我的尝试:

for item in mylist:
    if item[-2:] != '_C' or item[-x:] != '_C(INT)'
        print item

正如您所看到的，它不是很动态，我该如何解决这个问题？

Answer 1

您可以使用正则表达式:

import re

r = re.compile(r'_C\d+$')
mylist = ['summer_C','summer_C1','summer_P','summer_C123','summer_p32']
print [x for x in mylist if not r.search(x)]
#['summer_C', 'summer_P', 'summer_p32']
