Python – How to get only the numbers from a string which has got commas and hyphens in between

Consider like I have a string :

stringA = "values-are-10-1,20-2,30-1,40-4,50-3"

I need to get only the strings : desired output :

for stringA: 10-1,20-2,30-1,40-4,50-3

Could you please help me in getting regex for this.

>Solution :

I suggest you use regex module:

import re
stringA = "values-are-10-1,20-2,30-1,40-4,50-3"
re.sub("[^0-9\-\,]", "", stringA).strip("-")

Output

10-1,20-2,30-1,40-4,50-3
