Python Coding challenge - Day 243 | What is the output of the following Python Code?

 

Code:

s = 'clcoding.com'

index = s.find('com')

print(index)

Solution and Explanation: 

Explanation:

s = 'clcoding.com':

This defines a string variable s with the value 'clcoding.com'.

index = s.find('com'):

The find() method searches for the substring 'com' in the string s.

It returns the index of the first character of the first occurrence of the substring.

If the substring is not found, find() returns -1.

In this case, 'com' is present in 'clcoding.com', and it starts at index 9.

print(index):

This prints the value of index, which is 9.

String Breakdown:

The string 'clcoding.com' has characters at the following positions:

Index:  0 1 2 3 4 5 6 7 8 9 10 11

Chars:  c l c o d i n g . c  o  m

Here, the substring 'com' starts at index 9.

Output: 9

The find() method is useful for locating substrings within a string. In this case, it returns the index where 'com' begins.
