在python中的re.search中一起使用AND＆OR运算符？

Question

Is there a way to use AND & OR operator together in re.search in python?

if re.search(r'xyz|abc', line) != None:

Here I have used OR operator, But my requirement is to get line containing ( 'xyz' or 'abc' ) and 'pqr' . How to do that?

Answer 1

This works:

>>> import re
>>> re.search( r'(xyz|abc)pqr', 'abcpqr' )
<_sre.SRE_Match object at 0x7fa3055bdeb0>
>>> re.search( r'(xyz|abc)pqr', 'abcpq' )
>>> 

Answer 2

To ignore the order of the strings you can use

if re.search(r'(?=.*[pqr])(?=.*[xyz|abc])', line):
    print('match')

line = 'xyzpqr' # match
line = 'pqrxyz' # match

Answer 3

尝试这个：

re.search(r'((xyz|abc).*pqr)|(pqr.*(xyz|abc))', line)
