Match each Python data type to its description.
Drag a concept onto its matching description — or click a concept then click the description.
Whole numbers, e.g., 42
Numbers with decimal point, e.g., 3.14
Sequence of characters, e.g., 'hello'
Logical values True or False
Ordered, mutable collection of items
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
int: Whole numbers
The correct matches are: A (int - whole numbers), B (float - numbers with decimal point), D (bool - Boolean values True or False). Option C (str) is incorrect because strings are immutable sequences of characters, not mutable collections. Option E (list) is incorrect because lists are mutable collections, not immutable sequences. Option F (tuple) is incorrect because tuples are immutable sequences, not mutable collections.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
int: Whole numbers
Why this is correct
Correct. int represents whole numbers without decimal points.
float: Numbers with decimal point
Why this is correct
Correct. float represents numbers with a decimal point or in scientific notation.
str: Ordered, mutable collection of items
Why it's wrong here
Incorrect. This describes a list, not a string. A string is an immutable sequence of characters.
bool: Boolean values True or False
Why this is correct
Correct. bool represents logical values True and False.
list: Immutable sequence of characters
Why it's wrong here
Incorrect. This describes a string, not a list. A list is a mutable ordered collection.
tuple: Ordered, mutable collection of items
Why it's wrong here
Incorrect. This describes a list, not a tuple. A tuple is an immutable ordered collection.
