PCEP Computer Programming and Python Fundamentals Practice Question
Consider the code: x = 10; def func(): x = 5; print(x); func(); print(x). What is the output?
⚠ Common exam trap
The PCEP exam often tests the misconception that a variable assignment inside a function modifies the global variable, leading candidates to incorrectly choose options where both outputs are the same or the global value is overwritten.

Correct answer & explanation
✓
5 10
Inside the function `func()`, the local variable `x` is assigned the value 5, so `print(x)` inside the function outputs 5. After the function call, the global `x` remains 10, so the final `print(x)` outside the function outputs 10. This demonstrates Python's scoping rules where assignments inside a function create a local variable unless declared global.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
5 10
Why this is correct
Local scope inside function, global unchanged outside.
- ✗
5 5
Why it's wrong here
Would mean global x was changed.
- ✗
10 10
Why it's wrong here
Would mean local assignment didn't affect print inside function.
- ✗
10 5
Why it's wrong here
Would require global keyword inside function.
