Using AND & OR operator together in re.search in python?

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?

This works:

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

@Guy would not work with `hello world` either, so what? – lenik Jan 07 '20 at 06:35
The requirement is *containing ('xyz' or 'abc') and 'pqr'*. `'pqrabc'` should pass. – Guy Jan 07 '20 at 06:36
@Guy yep, in that particular order. whatever you're proposing is out of order – lenik Jan 07 '20 at 06:37

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

Try this:

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