Python Coding challenge - Day 613| What is the output of the following Python Code?

 

Code Explanation:

1. Function Definition

def chooser(val):

This line defines a function named chooser that takes a single argument val.

This function uses a generator (because of yield from used inside), which means it will produce values one at a time when iterated over, rather than returning a single value.

2. Conditional Logic with yield from

    if val == "a":

        yield from [1, 2]

If the input val is equal to the string "a", then:

yield from [1, 2] will yield each element from the list [1, 2] one by one.

So the generator would produce: 1, then 2.

    else:

        yield from [3, 4]

If the input val is anything other than "a", the else block runs.

It yields each element of the list [3, 4] one by one.

So it would produce: 3, then 4.

3. Calling the Generator and Printing Output

print(list(chooser("b")))

Here, the function chooser("b") is called with the argument "b".

Since "b" is not equal to "a", it follows the else path and yields 3, 4.

list(...) converts the generator's yielded values into a list: [3, 4].

print(...) then outputs that list to the console.

Final Output

[3, 4]
