Python Challenges: Calculate sum of all positive, negative integers present in a given string

Python Challenges - 1: Exercise-64 with Solution

Write a Python program to calculate sum of all positive, negative integers present in a given string.

Sample Solution-1:

Python Code:

from re import findall
def positive_negative_sum(str1):
    return sum(map(int, findall(r'\d+', str1))), sum(map(int, findall(r'-\d+', str1)))
str1 = '-100#^sdfkj8902w3ir021@swf-20'
print("Original string:")
print(str1)
print("\nSum of all positive, negative integers present in the said string:")
result = positive_negative_sum(str1)
print("Positive values:",result[0])
print("Negative values:",result[1])

Sample Output:

Original string:
-100#^sdfkj8902w3ir021@swf-20

Sum of all positive, negative integers present in the said string:
Positive values: 9046
Negative values: -120

Flowchart:

Sample Solution-2:

Python Code:

import re
def positive_negative_sum(str1):
    positive_values = sum(int(n) for n in re.findall('\d+', str1))
    negative_values = sum(int(n) for n in re.findall('-\d+', str1))
    return positive_values, negative_values

str1 = '-100#^sdfkj8902w3ir021@swf-20'
print("Original string:")
print(str1)
print("\nSum of all positive, negative integers present in the said string:")
result = positive_negative_sum(str1)
print("Positive values:",result[0])
print("Negative values:",result[1])

Sample Output:

Original string:
-100#^sdfkj8902w3ir021@swf-20

Sum of all positive, negative integers present in the said string:
Positive values: 9046
Negative values: -120
