I want to convert multiple characters to Python regular expressions

I want to convert only numbers in this str

"ABC234TSY65234525erQ"

I tried to change only areas with numbers to the * sign

This is what I wanted

"ABC*TSY*erQ"

But when I actually did it, it came out like this

"ABC***TSY********erQ"

How do I change it?

Thanks you!

>Solution :

use \d+. + in a regular expression means "match the preceding character one or more times"

import re
s = re.sub(r'\d+', '*', s)

output:

'ABC*TSY*erQ'
