Python Core Syntax 5

Question 1

What happens when you use `*args` in a function definition?

Accepted Answer

It collects extra positional arguments into a tuple

Answer

`*args` collects all extra positional arguments passed to the function into a tuple.

Question 2

What is the output of `print('ab' * 3)`?

Accepted Answer

'ababab'

Answer

Multiplying a string by an integer repeats it that many times, so `'ab' * 3` produces `'ababab'`.

Question 3

Which statement about Python indentation is correct?

Accepted Answer

Indentation defines code blocks and is syntactically required

Answer

Python uses indentation to delimit code blocks; incorrect or inconsistent indentation causes an `IndentationError`.

Question 4

What does the `	` escape sequence represent in a Python string?

Accepted Answer

A tab character

Answer

`	` is the escape sequence for a horizontal tab character in Python strings.

Question 5

Which of the following will raise a `TypeError` in Python?

Accepted Answer

'3' + 3

Answer

You cannot concatenate a string and an integer directly; `'3' + 3` raises a `TypeError` because the operands are of incompatible types.
