Last update on December 21 2024 07:45:06 (UTC/GMT +8 hours)

Write a Python program to find the occurrence and position of substrings within a string.

Sample Solution:

Python Code:

import re
text = 'Python exercises, PHP exercises, C# exercises'
pattern = 'exercises'
for match in re.finditer(pattern, text):
    s = match.start()
    e = match.end()
    print('Found "%s" at %d:%d' % (text[s:e], s, e))
	

Sample Output:

Found "exercises" at 7:16                                                                                     
Found "exercises" at 22:31                                                                                    
Found "exercises" at 36:45
