Python: Sum of all numerical values embedded in a sentence

Python Basic - 1: Exercise-56 with Solution

Write a Python program to sum of all numerical values (positive integers) embedded in a sentence.

Input:
Sentences with positive integers are given over multiple lines. Each line is a character string containing one-byte alphanumeric characters, symbols, spaces, or an empty line. However the input is 80 characters or less per line and the sum is 10,000 or less.

Sample Solution:

Python Code:

import sys,re
def test(stri):
  print("Input some text and numeric values (<ctrl-d> to exit):")
  print("Sum of the numeric values: ",sum([sum(map(int,re.findall(r"[0-9]{1,5}",stri)))]))

print(test("sd1fdsfs23 dssd56"))
print(test("15apple2banana"))
print(test("flowers5fruit5"))

Sample Output:

Input some text and numeric values ( to exit):
Sum of the numeric values:  80
None
Input some text and numeric values ( to exit):
Sum of the numeric values:  17
None
Input some text and numeric values ( to exit):
Sum of the numeric values:  10
None
