使用正則表達(dá)式，我想找出列表中的哪些元素以樣式 (yyyy-mm-dd) 結(jié)尾，例如 (2016-05-04) 等。模式 r'(2016-\d\d-\d\d)' 看起來不錯(cuò)，即使是天真。將它與 Endswith 結(jié)合的正確方法是什么？謝謝你。import rea_list = ["Peter arrived on (2016-05-04)", "Building 4 floor (2020)", "Fox movie (2016-04-04)", "David 2016-08-", "Mary comes late(true)"]style = r'\(2016\-\d\d\-\d\d\)'for a in a_list: if a.endswith(style): print a

您不能將正則表達(dá)式與字符串操作結(jié)合使用。只需用于re.search查找匹配并使用$模式中的錨點(diǎn)來檢查匹配是否發(fā)生在最后
>>> import re
>>> style = re.compile(r'\(2016-\d\d-\d\d\)$')
>>> for a in a_list:
... if style.search(a):
... print (a)
...
Peter arrived on (2016-05-04)
Fox movie (2016-04-04)

用 r'\(\d{4}-\d{2}-\d{2}\)$'
前任：
import re
a_list = ["Peter arrived on (2016-05-04)", "Building 4 floor (2020)", "Fox movie (2016-04-04)", "David 2016-08-", "Mary comes late(true)"]
style = r'\(\d{4}-\d{2}-\d{2}\)$'
for a in a_list:
if re.search(style, a):
print a
輸出：
Peter arrived on (2016-05-04)
Fox movie (2016-04-04)
