Python Coding challenge - Day 151 | What is the output of the following Python Code?

 

Let's break down the code:

s = 'clcoding'

index = s.find('n', -1)  

print(index)

s = 'clcoding': This line initializes a variable s with the string 'clcoding'.

index = s.find('n', -1): This line uses the find() method on the string s. The find() method searches for the specified substring within the given string. It takes two parameters: the substring to search for and an optional parameter for the starting index. If the starting index is negative, it counts from the end of the string.

In this case, 'n' is the substring being searched for.

The starting index -1 indicates that the search should start from the end of the string.

Since the substring 'n' is not found in the string 'clcoding', the method returns -1.

print(index): This line prints the value stored in the variable index, which is the result of the find() method. In this case, it will print -1, indicating that the substring 'n' was not found in the string 'clcoding'.

So, the overall output of this code will be -1.
