Question 122 of 498
PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
Which TWO of the following are valid Python data types?
⚠ Common exam trap
Python Institute often tests the distinction between Python's actual type names (`int`, `float`, `str`) and type names from other languages (like `string`, `char`, `double`), expecting candidates to know that Python uses `str` for strings and `float` for double-precision numbers, and has no separate `char` or `double` 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
✓
int
`int` is a built-in numeric data type in Python used to represent whole numbers without a fractional component. Python's `int` type has arbitrary precision, meaning it can handle arbitrarily large integers limited only by available memory.
