I want to find a unique ID in a string:

text = "Hello World, aaaa_dddd_bbbb_cccc"

The only defining feature of the unique ID is that it is a single word that contains three underscores. However, for the life of me I can't even start of figure out the regex for matching words with N non-consecutive instances of a certain character.

The best I can do is a hacky use of .split():

unique_id = None

for word in text.split(' '):
    if len(word.split("_")) > 2:
        unique_id = word

>>> text = "Hello World, aaaa_dddd_bbbb_cccc"

>>> re.search(r'(\w+_\w+){3}', text)
<_sre.SRE_Match object; span=(13, 32), match='aaaa_dddd_bbbb_cccc'>

The pattern matches one or more word characters followed by an underscore follwed by one or more word characters, three times.

From the docs:

{m}

Specifies that exactly m copies of the previous RE should be matched; fewer matches cause the entire RE not to match. For example, a{6} will match exactly six 'a' characters, but not five.

You can use regex findall to get a list of all items that match eg:

text = "Hello World, aaaa_dddd_bbbb_cccc, 1_2_3_4"

import re
found = re.findall(r'[^_ ]*_[^_ ]+_[^_ ]+_[^_ ]*',text)

print(found)
# -> ['aaaa_dddd_bbbb_cccc,', '1_2_3_4']

This allows strings starting and ending with a _ eg _1_2_3 if you don't want that you can change the first and last * to a +

The FIND function in Excel is used to return the position of a specific character or substring within a text string. The syntax of the Excel Find function is as follows: FIND( find_text, within_text, [start_num] ) The first 2 arguments are required, the last one is optional.


With straightforward regex pattern:

import re

s = "Hello World, aaaa_dddd_bbbb_cccc"
m = re.search(r'\b([^_\s]+_){3}[^_\s]+\b', s)
result = m.group() if m else m

print(result)

The output:

aaaa_dddd_bbbb_cccc

The pattern could be more strict (depends on what characters are allowed) like:

...
m = re.search(r'\b([a-z0-9]+_){3}[a-z0-9]+\b', s, re.I)
