Python Coding Challange - Question with Answer (01300925)

Explanation:

1. Initialization:

a, b = 0, 1 → We start with two variables:
a = 0 (first Fibonacci number)
b = 1 (second Fibonacci number)

2. Loop:

for _ in range(3): → Repeat the following 3 times. _ is just a placeholder since we don’t use the index.

3. Printing the current number:

print(a, end=" ") → Prints the current value of a on the same line with a space.

4. Updating the numbers:
a, b = b, a + b → Updates both variables simultaneously:
a becomes the old value of b
b becomes the sum of old a + b (next Fibonacci number)

5. Final Output:

0 1 1

Key Concept:

This uses tuple unpacking (a, b = b, a + b) to update two variables simultaneously without a temporary variable, which is a common Python trick for generating sequences like Fibonacci.
