Python Coding challenge - Day 64 | What is the output of the following Python code?



s = set()
s.update('hello', 'how', 'are', 'you?')

Solution - 

The above code counts the total number of unique characters in the given strings. Here's the breakdown:

Create an empty set s:

s = set()

This line initializes an empty set s.

Update the set with multiple string arguments using the update method:

s.update('hello', 'how', 'are', 'you?')

In this line, you're using the update method to add the characters from the strings 'hello', 'how', 'are', and 'you?' to the set s.

Print the length of the set:


This line prints the length (number of elements) of the set s using the len function. Since each character is considered unique, the length will be the total number of unique characters in the combined strings.

The output will be 10 because it counts the total number of unique characters in the provided strings. Thank you for pointing this out.
