PCEP Computer Programming and Python Fundamentals Practice Question

Exhibit

Refer to the exhibit.

```
x = '10'
y = 5
result = x + y
print(result)
```

What is the output of the code in the exhibit?

⚠ Common exam trap

Python Institute often tests the misconception that Python will automatically convert types (like JavaScript or PHP do), leading candidates to expect either concatenation or addition instead of recognizing that Python raises a TypeError for incompatible operand types.

Answer choices

Why each option matters

Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.

Correct answer & explanation

✓

TypeError

The code attempts to concatenate a string ('10') and an integer (5) using the + operator. In Python, the + operator does not implicitly convert types; it raises a TypeError because it cannot determine whether to perform string concatenation or integer addition. This is a fundamental rule of Python's strong typing system.
