What is Data Types in python ? | Type of Data Types

What is Data type?

• A data type shows what kind of data is being used.
• The type() function can be used to determine which type of data.

Example:

Number = 5

Here, 5 is an integer assigned to the variable, so data type of number is int class.

Types of data types:

Numeric (int, float, complex): Stores numbers.

Example Program:

# int
number1 = 5
print(number1, 'is type of', type(number1))

# float
number2 = 6.0
print(number2, 'is type of', type(number2))

# complex
number3 = 7+8j
print(number3, 'is type of', type(number3))

output:

5 is type of <class 'int'>
6.0 is type of <class 'float'>
(7+8j) is type of <class 'complex'>

String (str): Stores text.

Example Program:

text = "Hello"
print(text, 'is type of', type(text))

output:

Hello is type of <class 'str'>

Sequence (list, tuple, range): Stores a collection of items.

Example Program:

# List
my_list = [1, 2, 3]
print(my_list, 'is type of', type(my_list))

# Tuple
my_tuple = (1, 2, 3)
print(my_tuple, 'is type of', type(my_tuple))

# Range
my_range = range(3)
print(my_range, 'is type of', type(my_range))

output:

[1, 2, 3] is type of <class 'list'>
(1, 2, 3) is type of <class 'tuple'>
range(0, 3) is type of <class 'range'>

Mapping (dict): Stores data in key-value pairs.

Example Program:

my_dict = {'a': 1, 'b': 2}
print(my_dict, 'is type of', type(my_dict))

output:

{'a': 1, 'b': 2} is type of <class 'dict'>

Boolean (bool): Stores True or False.

Example program:

my_bool = True
print(my_bool, 'is type of', type(my_bool))

output:

True is type of <class 'bool'>

Set (set, frozenset): Stores unique items.

Example program:

# Set
my_set = {1, 2, 3}
print(my_set, 'is type of', type(my_set))

# Frozenset
my_frozenset = frozenset([1, 2, 3])
print(my_frozenset, 'is type of', type(my_frozenset))

output:

{1, 2, 3} is type of <class 'set'>
frozenset({1, 2, 3}) is type of <class 'frozenset'>
