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 regeximport re # initializing stringtest_str = "gfg + 4-1is + 5best-8" # printing original stringprint("The original string is : " + test_str) # Segregate Positive and Negative Integers# Using regexres = re.findall('[-+]?\d+', test_str) # printing result print("The split string is : " + str(res)) |
The original string is : gfg+4-1is+5best-8 The split string is : ['+4', '-1', '+5', '-8']
