PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
What is the output of the following code? ```python
print('Hello', 'World', sep='-')```
⚠ Common exam trap
Many candidates assume the default space separator is used or misread the hyphen as a space, leading them to choose 'Hello World' instead of recognizing the explicit `sep='-'` override.

Why each option matters

Correct answer & explanation
✓
Hello-World
The `print()` function's `sep` parameter specifies the separator between multiple arguments. By default, `sep` is a space, but here it is explicitly set to `'-'`, so the output joins 'Hello' and 'World' with a hyphen, producing 'Hello-World'. Option D is correct because the hyphen is placed directly between the two strings without any extra spaces.
