Answer 1

Another possible solution, in case you're looking for all the words in a given string, which contain a number

Pattern

\w*\d{1,}\w*

• \w* - Matches 0 or more instances of [A-Za-z0-9_]
• \d{1,} - Matches 1 or more instances of a number
• \w* - Matches 0 or more instances of [A-Za-z0-9_]

The whole point in \w* is to allow not having a character in the beginning or at the end of a word. This enables capturing the first and last words in the text.

If the goal here is to only get the numbers without the words, you can omit both \w*.

Given the string

Hello world 1 4m very happy to be here, my name is W1lly W0nk4

Matches

1 4m W1lly W0nk4
