Python Coding Challange - Question with Answer (01241025)

 

Step 1: Loop Execution

for i in range(3): 
    x = i

• The loop runs 3 times — for i = 0, 1, and 2.

• Each time, x is assigned the value of i.

• After the loop finishes, x remains as the last value assigned → x = 2.

So now:

x = 2

🔹 Step 2: Function Definition

def test(): 
    print(x)

This defines a function named test, but it doesn’t execute yet.

🔹 Step 3: Function Call

test()

When test() runs:

• Python looks for the variable x inside the function (local scope).

• It doesn’t find one, so it looks outside the function (global scope).

• There it finds x = 2.

✅ Output:

2
 Key Concept — Scope:

• Local scope: Variables declared inside a function.

• Global scope: Variables declared outside functions.

• If a function doesn’t have a local variable with the same name, it uses the global variable.
