PCEP Computer Programming and Python Fundamentals Practice Question

Exhibit

Refer to the exhibit.
# Python script: convert.py
x = input('Enter number: ')
y = x * 2
print(y)
--- End of exhibit ---

Consider the following code:

x = input('Enter a number: ')

print(x + x)

A user enters 5 at the prompt. What is printed?

⚠ Common exam trap

The PCEP exam often tests the distinction between string concatenation and numeric addition, exploiting the fact that `input()` returns a string, so candidates mistakenly assume automatic type conversion to integer.

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

✓

55 because Python's input() function returns a string. When the user enters 5, it is stored as the string '5'. If the code then uses the + operator to concatenate this string with itself (e.g., print(input() + input()) or print(x + x)), the result is '55', not numeric addition.
