start() & end()
These expressions return the indices of the start and end of the substring matched by the group.
>>> import re >>> m = re.search(r'\d+','1234') >>> m.end() 4 >>> m.start() 0
You are given a string S.
Your task is to find the indices of the start and end of string k in S.
Input Format :
The first line contains the string S.
The second line contains the string k.
- 0 < len(s) < 100
- 0 < len(k) < len(s)
Output Format :
Print the tuple in this format: (start _index, end _index).
If no match is found, print (-1, -1).
Sample Input :
Sample Output :
(0, 1) (1, 2) (4, 5)
Re.start() & Re.end() in Python – HackerRank Solution
import re S, k = input(), input() matches = re.finditer(r'(?=(' + k + '))', S) anymatch = False for match in matches: anymatch = True print((match.start(1), match.end(1) - 1)) if anymatch == False: print((-1, -1))
