Python Coding challenge - Day 52 | What is the output of the following Python code?



Code - 


numbers = [1, 2, 3]
for num in numbers:
    print(num)

Solution - 


Step-by-step explanation of the code:

List Definition: You start by defining a list named numbers containing three integers: 1, 2, and 3.
numbers = [1, 2, 3]
This line creates a list with the values [1, 2, 3] and assigns it to the variable numbers.

For Loop: You then use a for loop to iterate over the elements in the numbers list.
for num in numbers:

This loop will go through each element of the numbers list, and for each iteration, the current element is assigned to the variable num.

Print Statement: Inside the loop, you have a print statement.
print(num)

This line prints the value of num to the console.

Iteration: The loop executes three times, once for each element in the numbers list.

  1. In the first iteration, num is 1, and it is printed to the console.
  2. In the second iteration, num is 2, and it is printed to the console.
  3. In the third iteration, num is 3, and it is printed to the console.
Output: As a result, the code will print each number in the numbers list on a separate line.

The output will be:

1
2
3

Each number is printed on a new line, so the output displays:
1
2
3

That's the step-by-step explanation of the provided Python code. It simply prints the elements of the numbers list, one at a time, on separate lines.
