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

In the code:

s = 'clcoding.com'
index = s.find('com')
print(index)

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.
