200-901 Software Development and Design Practice Question
Which TWO of the following are valid Python data types?
⚠ Common exam trap
Cisco often tests the distinction between built-in data types (like list and dict) and modules or functions (like array and map) that are not data types themselves, causing candidates to confuse the array module or map function with actual data 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
✓
list
List and set are both built-in Python data types. List is an ordered, mutable collection, while set is an unordered collection of unique elements. Array is not a built-in data type; it is provided by the array module. Dict is also a built-in data type, but the question requires selecting exactly two options, and list and set are the correct ones. Map is a built-in function, not a data type.
