Basic Data Types in Python

The data type is 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.

The data type is like a specification about the type of data you want to store in memory, and python has several built-in data types:

• String text type: str
• Numeric types: 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 categorize all these data types using the function type() to display the data type of the variable.

Text format

String data type str

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

Eg:

Result:

Hello, world!
<class 'str'>

Number type

Integer data type int

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

Eg:

Result:

4
<class 'int'>

float . real number data type

float stands for real number (decimal).

Eg:

Result:

3.14
<class 'float'>

A complex number has a real and imaginary part, each of which is a real number. Complex numbers can be written in two forms: real + (imag)jcomplex(real, imag).

Eg:

Result:

(5+10j)
<class 'complex'>

Sequence type data type

list

List (list) is a data type where you can store a set of data. List can also contain different data types. Lists can also sort, change elements, and allow duplicates

Eg:

Result:

['Captain America', 'Iron Man', 'Thor', 'Hulk', 'Black Widow', 'Hawkeye']
<class 'list'>

tuple

Tuple is a data type where you can store a collection of data. Tuples can also contain different data types. Tuples are sortable, cannot change elements, and allow elements to be duplicated.

Eg:

Result:

('Captain America', 'Iron Man', 'Thor', 'Hulk', 'Black Widow', 'Hawkeye')
<class 'tuple'>

range

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

Eg:

Result:

range(0, 10)
<class 'range'>

Mapped data type

dict

dict stands for dictionary in python. Dict is used to store data values ​​in key:values. Dict is an unordered, mutable set, and no duplicates are allowed.

Eg:

Result:

{'Learning': 'Programming', 'Language': 'Python', 'Day': 4}
<class 'dict'>

Data type Set

set

set is a data type where you can hold a set of data. Set can also contain different data types. Set is unordered and unindexed and does not allow duplicate elements.

Eg:

Result:

{'Black Widow', 'Iron Man', 'Thor', 'Hawkeye', 'Hulk', 'Captain America'}
<class 'set'>

frozenset

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

Eg:

Result:

frozenset({'cherry', 'banana', 'apple'})
<class 'frozenset'>

Boolean type

bool

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

Eg:

Result:

True
<class 'bool'>
False
<class 'bool'>

Binary type

bytes

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

Eg:

Result:

b'hello'
<class 'bytes'>
b'Hello'
<class 'bytes'>

bytearray

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

Eg:

Result:

bytearray(b'\x00\x00\x00\x00')
<class 'bytearray'>

memoryview

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

Eg:

Result:

<memory at 0x2b4f7a8a7408>
<class 'memoryview'>

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')
<memory at 0x2b8346a29408>
