Python Data Type
Data Type
Data type is an Important Concept In Programming
Variables can store data of different types, and different types can do different things.
Python has the following data types built-in by default, in these categories:
| Text Type | str |
| Numeric type | int, float, complex |
| Sequence Types | list, tuple, range |
| Mapping Type | dict |
| Set Types | set, frozenset |
| Boolean Type | bool |
| Binary Types | bytes, bytearray, memoryview |
| None Type | NoneType |
How to Get the Data Type of any Value ?
You can get the data type of any object by using the type() function:
x = 5
print(type(x))

Setting the Data Type
In Python, the data type is set when you assign a value to a variable:
| Example | Data Type |
|---|---|
| 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 = frozenset({"apple", "banana", "cherry"}) | frozenset |
| x = True | bool |
Setting the Specific Data Type
If you want to specify the data type, you can use the following constructor functions:
| Example | Data Type |
|---|---|
| x = str("Hello World") | str |
| x = int(20) | int |
| x = float(20.5) | float |
| x = complex(1j) | complex |
| x = list(("apple", "banana", "cherry")) | list |
| x = tuple(("apple", "banana", "cherry")) | tuple |
| x = range(6) | range |
| x = dict(name="John", age=36) | dict |
| x = set(("apple", "banana", "cherry")) | set |
| x = frozenset(("apple", "banana", "cherry")) | frozenset |
| x = bool(5) | bool |
| x = bytes(5) | bytes |
| x = bytearray(5) | bytearray |
| x = memoryview(bytes(5)) | memoryview |
