Python Data Types

Python Data Types

In programming, data type is an important concept. Variables can store data of different types, and different types can do different things.

Built-in Data Types

Python has the following data types built-in by default:

• Text Type: str
• Numeric Types: int, float, complex
• Sequence Types: list, tuple, range
• Mapping Type: dict
• Set Types: set, frozenset
• Boolean Type: bool
• Binary Types: bytes, bytearray, memoryview

Getting the Data Type

You can get the data type of any object by using the type() function:

x = 5
print(type(x))  # <class 'int'>

x = "Hello World"
print(type(x))  # <class 'str'>

x = 20.5
print(type(x))  # <class 'float'>

Setting the Data Type

In Python, the data type is set when you assign a value to a variable:

x = "Hello World"  # str
x = 20            # int
x = 20.5          # float
x = 1j            # complex
x = ["apple", "banana", "cherry"]  # list
x = ("apple", "banana", "cherry")  # tuple
x = range(6)      # range
x = {"name" : "John", "age" : 36}  # dict
x = {"apple", "banana", "cherry"}  # set
x = True          # bool
