。例如，在“/gallery/haha/nika/7907/08-2015”中找到“nika”
I wrote this in my python code:
>>> text = '/gallery/haha/nika/7907/08-2015'
>>> re.findall(r'/[a-zA-Z]*/$', text)
but I got an empty list:
[]
And if I delete that dollar sign:
>>> re.findall(r'/[a-zA-Z]*/', text)
The return list is not empty but '/haha/' is missed:
['/gallery/', '/nika/']
有人知道为什么吗？
最佳答案
Use lookarounds as in
re.findall(r'(?<=/)[a-zA-Z]*(?=/)', text)
See demo
$表示字符串结束，因此您将得到空字符串。。。
