29. Numbers and Positions

Write a Python program to separate and print the numbers and their position in a given string.

Sample Solution:

Python Code:

import re
# Input.
text = "The following example creates an ArrayList with a capacity of 50 elements. Four elements are then added to the ArrayList and the ArrayList is trimmed accordingly."

for m in re.finditer("\d+", text):
    print(m.group(0))
    print("Index position:", m.start())
	

Sample Output:

50                                                                                                            
Index position: 62
