From resume text, I want to extract the number of years of experience of a candidate.

How I intended on obtaining this-->
Years of experience is usually mentioned as '4 Years' or '6+ years' or '4.8 year'.

What I have tried:

exp_p='[^\d]*(\d*\+? years|Years|year|Year)'


Expected Output-
'x years'


I'm getting the expected output only when the experience number is follwed by "years".


This expression works only for the first word in the series of 'or' conditions, i.e., "years" in this context. Why isn't the 'or' operator working as expecting?

Try this:
\d*\.?\d*\+?\s+(?:[Yy]ears|[Yy]ear)

Thank you. It works.

Instead of
Python
exp_p='[^\d]*(\d*\+? years|Years|year|Year)'

Try
Python
exp_p='\d+(\.\d+)\s*(years|Years|year|Year)'


Just a few interesting links to help building and debugging RegEx.
Here is a link to RegEx documentation:
perlre - perldoc.perl.org[^]
Here is links to tools to help build RegEx and debug them:
.NET Regex Tester - Regex Storm[^]
Expresso Regular Expression Tool[^]
RegExr: Learn, Build, & Test RegEx[^]
Online regex tester and debugger: PHP, PCRE, Python, Golang and JavaScript[^]
This one show you the RegEx as a nice graph which is really helpful to understand what is doing a RegEx: Debuggex: Online visual regex tester. JavaScript, Python, and PCRE.[^]
This site also show the Regex in a nice graph but can't test what match the RegEx: Regexper[^]

You do not need the 's' at the end of Year or year.

In question, the 's' is part of the output.

Oops - my apologies.
