Posting Etiquette

  1. Ask the main part of your question in the title. This should be concise but informative.

  2. Provide everything up front. Don't make people fish for more details in the comments. Provide background information and examples.

  3. Be present for follow up questions. Don't ask for help and run away. Stick around to answer questions and provide more details.

  4. Ask about the problem you're trying to solve. Don't focus too much on debugging your exact solution, as you may be going down the wrong path. Include as much information as you can about what you ultimately are trying to achieve. See more on this here: https://xyproblem.info/

hello guys. i am trying to match one or more digit from end of string

import re

print(re.match(r'\d+$', "hello001"))
print(re.match(r'[0-9]+$', "hello001"))

output None from both print statement. I've tried my regex on regex101.com and it seems working probably.

From the python docs:

Note that even in MULTILINE mode, re.match() will only match at the beginning of the string and not at the beginning of each line.

If you want to locate a match anywhere in string, use search() instead (see also search() vs. match()).
