Python Coding challenge - Day 51 | What is the output of the following Python code?

 


Code - 

r = [20, 40, 60, 80]

r[1:4] = []

print(r)

Detailed Solution - 

initialize a list called r with four elements:

r = [20, 40, 60, 80]

Attempt to modify the list by removing elements using a slice. The slice notation used is [1:4], which means it will remove elements starting from index 1 (inclusive) up to index 4 (exclusive).

The list r is modified as follows:
  1. Remove the element at index 1 (which is 40).
  2. Remove the element at index 2 (which is 60).
  3. Remove the element at index 3 (which is 80).
After the modifications, the list r will now look like this:
r = [20]

Finally, the code prints the modified list:
[20]

So, the step-by-step solution demonstrates that the code removes elements 40, 60, and 80 from the list r, leaving only the element 20 in the list.
