    It really tests your understanding of slicing and string traversal. If you're practicing for interviews or just want to strengthen your Python basics, Gurubhai247

    string.count(sub_string) why this logic gives only 1

    def count_substring(string, sub_string):

    count = 0
index = 0       
while index < len(string):
    found_at = string.find(sub_string, index)
    if found_at == -1:
        break
    count += 1
    index = found_at + 1
return count
    if __name__ == '__main__':
string = input().strip()
sub_string = input().strip()

count = count_substring(string, sub_string)
print(count)
