Python Coding challenge - Day 615| What is the output of the following Python Code?

 

Code Explanation:

1. Defining the Generator Function

def logic():

This line defines a function named logic.

The function will use a yield statement, which makes it a generator function.

A generator function returns an iterator that yields values one at a time using the yield keyword.

2. Outer Loop

    for i in range(2):

This is a for loop that iterates over the range from 0 to 1 (since range(2) generates [0, 1]).

The variable i will take the values 0 and then 1.

3. Inner Loop

        for j in range(2):

For each value of i, another loop runs where j takes the values 0 and then 1.

This forms a nested loop, so you get all combinations of i and j.

4. Yielding a Tuple

            yield (i, j)

Instead of returning a value immediately, this line yields a tuple (i, j) to the caller.

yield pauses the function and sends the value back, resuming from the same point the next time it's called.

This will yield the following 4 tuples over all iterations: (0, 0), (0, 1), (1, 0), (1, 1).

5. Printing the Results

print(list(logic()))

logic() returns a generator object.

Wrapping it with list() forces the generator to evaluate all its values and return them as a list.

The output will be:

[(0, 0), (0, 1), (1, 0), (1, 1)]

Final Output

[(0, 0), (0, 1), (1, 0), (1, 1)]
