Python Regular Expression: Exercise-21 with Solution

Write a Python program to find the substrings within a string.

Note: There are two instances of exercises in the input string.

Sample Solution:-

Python Code:

import re
text = 'Python exercises, PHP exercises, C# exercises'
pattern = 'exercises'
for match in re.findall(pattern, text):
    print('Found "%s"' % match)
