Extract/Match string with "_" inbetween 2 words-CodePudding

I'm trying to extract any strings with a "_" in the middle.

For example, with name1_name2 _ nothing test1 _ test 2_ _3 I would like to extract name1_name2

Thank you for reading!

>>> import re
>>> s = 'name1_name2 _ nothing test1 _ test 2_ _3 name3_name4'
>>> re.findall('[a-zA-Z0-9] _[a-zA-Z0-9] ', s)
['name1_name2', 'name3_name4']
>>> re.findall('\w _\w ', s)
['name1_name2', 'name3_name4']

How's this?

[\w] _[\w]

Does that work for you?

You can use regex given below and it will select any string having single _ in its name.

^\S [_]\S
