Python Coding challenge - Day 624| What is the output of the following Python Code?

 

Code Explanation:

Function Definition

def safe_gen():

This defines a generator function named safe_gen.

It will yield values one at a time using the yield keyword.

Try Block Starts

    try:

Begins a try block to handle exceptions that may occur during the yield statements.

First Yield

        yield 1

The first value 1 is yielded successfully.

The generator pauses here and waits for the next iteration.

Second Yield — Division by Zero

        yield 2 / 0

When execution resumes, it tries to compute 2 / 0, which raises a ZeroDivisionError.

The error is caught by the except block, and this yield never completes.

Third Yield (Skipped)

        yield 3

This line is never executed, because control jumps to the except block once the exception is raised.

Exception Handling

    except ZeroDivisionError:

        yield "Error caught"

This catches the ZeroDivisionError from 2 / 0.

Instead of crashing, it yields the string "Error caught".

Calling and Printing

print(list(safe_gen()))

This runs the generator and collects all yielded values into a list:

First, 1 is yielded.

Then 2 / 0 causes an exception.

Instead of stopping, "Error caught" is yielded from the except block.

yield 3 is skipped due to the error.

Final Output

[1, 'Error caught']
