How to split a string of numbers and letters into a list of strings and a list of numbers

Given a string containing a sequence of letters and numbers (such as):

"GHG-H89KKK90KKP"  

Do we have any way to split this string into two lists, one containing the letters and one containing the numbers?

["GHG-H", "KKK", "KKP"] 
[89,90]

>Solution :

Use re.findall from the re (regular expressions) library to find patterns in the string. The first expression (?i)[a-z|\-]+ finds all sequences of letters (ignoring case), it also includes hyphens (-). The second expression [0-9]+ finds all sequences of numbers in your string.

import re

string = "GHG-H89KKK90KKP"

print(re.findall("(?i)[a-z|-]+", string))
print(re.findall("[0-9]+", string))

Output:

['GHG-H', 'KKK', 'KKP']
['89', '90']
