Python Coding Challenge - Question with Answer (ID 170926)

 

Code Explanation:

1. Assigning the Initial Value

x = 5

A variable x is created.

Its value is 5.

x = 5

2. Creating the Lambda Function

f = lambda n=x: n

This is the tricky part. 👀

The lambda has a parameter n.

n=x means x is used as the default value.

At this moment, x is 5.

So Python effectively stores:

n = 5

The lambda is equivalent to:

def f(n=5):

    return n

3. Changing x

x = 9

Now the outside variable becomes:

x = 9

⚠️ But this does not change the default value already stored inside the lambda.

The lambda still has:

n = 5

4. Calling the Function

f()

No argument is provided, so Python uses the stored default:

n = 5

Therefore:

f() → 5

5. Printing the Result

print(f())

The function returns 5, so the output is:

Final Output:

5
