Python | Segregate Positive and Negative Integers from mixed string

Sometimes, while working with Python strings of data, we can have a problem in which we need to separate positive and negative integers in a string. This can occur in many domains that include data handling. Lets discuss certain way in which we can solve this problem.

Method : Using regex
This problem can be solved using appropriate regex. In this, we match the matching regex with string and separate the positive integers and negative integers from the string.

# Python3 code to demonstrate working of  
# Segregate Positive and Negative Integers 
# Using regex 
import re 
  
# initializing string 
test_str = "gfg + 4-1is + 5best-8"
  
# printing original string 
print("The original string is : " + test_str) 
  
# Segregate Positive and Negative Integers 
# Using regex 
res = re.findall('[-+]?\d+', test_str) 
  
# printing result  
print("The split string is : " + str(res))  

Output :

The original string is : gfg+4-1is+5best-8
The split string is : ['+4', '-1', '+5', '-8']
