Python Coding challenge - Day 176 | What is the output of the following Python Code?

 

Code: 

x = [1, 2, 3]

y = x.copy()

x[0] = 4

print(y)

Solution and Explanation: 

let's break down what happens in the code:

x = [1, 2, 3]: This line initializes a list x with elements [1, 2, 3].

y = x.copy(): This line creates a copy of the list x and assigns it to the variable y. This means y now holds a separate list with the same elements as x.

x[0] = 4: This line changes the first element of the list x to 4. So now x becomes [4, 2, 3].

print(y): This line prints the list y.

The output of this code will be [1, 2, 3]. Even though we changed the first element of x, it doesn't affect the list that y refers to, because y is a separate copy of x created earlier.
