正则表达式将单词与数字匹配，但如果仅数字则不匹配

Question

I would like to match a word that may contain numbers but not if it's numbers only.

For example:

Menial = match

John124 = match

V4n3ss4 = match

0livia = match

3715 = no match

I have tried \\w* but surprisingly, this takes a plain number as a word. I also tried other patterns with \\b but I noticed that, for some reason, a single number is also considered a "word boundary".

Answer 1

One approach to force a letter somewhere in the middle of the match is to put [A-Za-z] in between \\w* expressions, like this:

\b\w*[A-Za-z]\w*\b

\\b s on both ends ensure that the matches are at word boundaries.

Demo.

Answer 2

Try: \\w*[a-zA-Z]\\w*

This is essentially "At least one non-digit character surrounded by any number of alphanumeric characters"
