PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
Which THREE of the following are built-in Python data types? (Choose three.)
⚠ Common exam trap
Python Institute often tests the distinction between built-in types and types available only through modules, so candidates mistakenly choose `array` or `boolean` because they sound familiar, but Python uses `bool` and requires importing `array`.
