PCEP Practice Question: Data Types, Variables, Basic I/O and Operators

A junior developer writes: print('Hello' + 5). This code raises an error. What is the best way to fix it?

⚠ Common exam trap

Python Institute often tests the distinction between concatenation (`+`) and multiple arguments in `print()`, where candidates may think `print('Hello', 5)` produces `Hello5` instead of `Hello 5` due to the default `sep=' '` parameter.

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

print('Hello' + str(5))

Python's `+` operator for strings requires both operands to be strings. The code `print('Hello' + 5)` raises a `TypeError` because it attempts to concatenate a string with an integer. Using `str(5)` converts the integer to the string `'5'`, allowing the concatenation to succeed and print `Hello5`.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • print('Hello' * 5)

    Why it's wrong here

    Repeats 'Hello' 5 times, not concatenation.

  • print('Hello' + str(5))

    Why this is correct

    Converts integer 5 to string and concatenates.

  • print('Hello', 5)

    Why it's wrong here

    Prints two separate items with a space, not concatenation.

  • print('Hello' + '5')

    Why it's wrong here

    This works but changes the value to string '5', not the integer.
