What are the different data types in Python?

Question

Accepted Answer

Different data types in Python include integers, floats, strings, lists, tuples, dictionaries, and booleans.

Integers: whole numbers without decimals (e.g. 5, -10)
Floats: numbers with decimals (e.g. 3.14, -0.5)
Strings: sequences of characters enclosed in quotes (e.g. 'hello', '123')
Lists: ordered collections of items (e.g. [1, 'apple', True])
Tuples: ordered, immutable collections of items (e.g. (1, 'banana', False))
Dictionaries: unordered key-value pairs (e.g. {'key': 'value', 'name': 'Alice'})
Booleans: True or False values representing truth or falsehood

Accepted Answer

Python has several built-in data types, including:
1. Numbers: Python supports integers, floating-point numbers, and complex
numbers. These data types can be used for arithmetic operations, such as
addition, subtraction, multiplication, and division.
2. Strings: Strings are used to represent text data in Python. They can be
enclosed in single or double quotes, and can be manipulated using various
string methods.
3. Lists: Lists are used to store a collection of values, which can be of
different data types. They are mutable, which means that their contents
can be changed.
4. Tuples: Tuples are similar to lists, but they are immutable, which means
that their contents cannot be changed once they are created.
5. Sets: Sets are used to store a collection of unique values. They are
mutable and unordered, which means that their elements are not indexed.
6. Dictionaries: Dictionaries are used to store key-value pairs. They are
mutable and unordered, and can be used to efficiently store and retrieve
data based on keys.
7. Booleans: Booleans are used to represent logical values, such as True or
False. They are often used in conditional statements and loops to control
program flow.
8. None: None is a special value in Python that represents the absence of a
value. It is often used as a placeholder or to indicate that a variable has not
been assigned a value yet.
