Basic data types in Python

Data types are one of the most important components of python. You can do a lot of interesting things with these data types. It is a fact that in python, all data types are objects.

Data type is like a characteristic of the type of data you want to store in memory and python has some of the following built-in data types:

• String text type: str
• Number type: int, float, complex
• Sequence types: list, tuple, range
• Mapping type: dict
• Set data type: set, frozenset
• Boolean type: bool
• Binary type: byte, bytearray, memoryview

Now, let’s classify all these data types using functions type() to display the variable’s data type.

Text format

String data type str

str is short for string used to store text in python. Strings can be written in double or single quotes, so you can write like this:

For example:

Result:

Hello, world!

Number type

Integer data type int

int is short for integer (integer) used to store integers (positive and negative integers).

For example:

Result:

4

Float real number data type

float stands for real number (decimal number).

For example:

Result:

3.14

Complex numbers have real parts and imaginary parts, each part is a real number. Complex numbers can be written in two forms: real + (imag)jcomplex(real, imag).

For example:

Result:

(5+10j)

Sequence type data type

list. list

List is a data type where you can store a collection of data. List can also contain different data types. List can also sort, change elements and allow elements to appear duplicated

For example:

Result:

['Captain America', 'Iron Man', 'Thor', 'Hulk', 'Black Widow', 'Hawkeye']

tuple

Tuple is a data type where you can store a collection of data. Tuples can also contain different data types. Tuples are sortable, elements cannot be changed, and duplicate elements are allowed.

For example:

Result:

('Captain America', 'Iron Man', 'Thor', 'Hulk', 'Black Widow', 'Hawkeye')

range. range

The range type represents an immutable (unchangeable) series of numbers. Usually used to repeat a specific number of times in a for loop.

For example:

Result:

range(0, 10)

Mapping data type

dict

dict is short for dictionary in python. Dict is used to store data values ​​in key:values. A Dict is an unordered, mutable collection that does not allow duplicates.

For example:

Result:

{'Learning': 'Programming', 'Language': 'Python', 'Day': 4}

Data type Set

set

set is a data type where you can contain a collection of data. Sets can also contain different data types. Sets are unordered and unindexed, and duplicate elements are not allowed.

For example:

Result:

{'Black Widow', 'Iron Man', 'Thor', 'Hawkeye', 'Hulk', 'Captain America'}

frozenset

The frozenset data type can be created by the function frozenset(). Jaw frozenset() accepts an iterable object and returns an immutable frozenset object (like a set object, just immutable).

For example:

Result:

frozenset({'cherry', 'banana', 'apple'})

Boolean type

bool

bool stands for boolean in python. Booleans represent one of two values: True or False.

For example:

Result:

True

False

Binary type

bytes

The byte data type can be created in two forms: using the byte() function or using the prefix “b”.

For example:

Result:

b'hello'

b'Hello'

bytearray

Jaw bytearray() returns a bytearray object. It can convert objects to bytearray objects.

For example:

Result:

bytearray(b'\x00\x00\x00\x00')

memoryview

jaw memoryview() returns an object in memory view of a specified object.

For example:

Result:

Hello, World!
4
3.14
(5+10j)
['Captain America', 'Iron Man', 'Thor', 'Hulk', 'Black Widow', 'Hawkeye']
('Captain America', 'Iron Man', 'Thor', 'Hulk', 'Black Widow', 'Hawkeye')
range(0, 10)
{'Learning': 'Programming', 'Language': 'Python', 'Day': 4}
{'apple', 'cherry', 'banana'}
frozenset({'banana', 'cherry', 'apple'})
True
False
b'\x00\x00\x00\x00'
bytearray(b'\x00\x00\x00\x00')

Frequently asked questions

How many basic data types does Python have?

Python provides many basic data types, including numeric types (int, float, complex), string types (str), sequence types (list, tuple, range), map types (dict), set types (set, frozenset), Boolean types (bool), and binary types (bytes, bytearray, memoryview).

How to determine the data type of a variable in Python?

Use functions type(). For example: type(my_variable) will return the data type of the variable my_variable.

What is the difference between list and tuple in Python?

Both list and tuple are sequential data types, but list is mutable and tuple is immutable. This means you can add, remove, or modify elements in a list, but you can’t do that with a tuple.
