Python Data Types:
In programming world data types are important concept.
The variables are stored different types of data to make the type is defined.
So, python has following in-built data-types are as,
| 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 |
How To Know The Data Type Of Variable?
Using type() function, we can get the data type of any object.
Example:
#print the type of variable x x = 5 print(type(x))
The output of above code is,
<class 'int'>
In python, when we assigning a value the data type is set.
Below Examples is Return Type When Value is Assign:
#Example-1 x = "Hello World" #display x: print(x) #display the data type of x: print(type(x))
#Output Hello World <class 'str'>
#Example-2 x = 20 #display x: print(x) #display the data type of x: print(type(x)) #output 20 <class 'int'>
#Example-3 x = 20.5 #display x: print(x) #display the data type of x: print(type(x)) #Output 20.5 <class 'float'>
#Example-4 x = 1j #display x: print(x) #display the data type of x: print(type(x)) #Output 1j <class 'complex'>
#Example-5 x = ["apple", "banana", "cherry"] #display x: print(x) #display the data type of x: print(type(x)) #Output ["apple", "banana", "cherry"] <class 'list'>
#Example-6
x = ("apple", "banana", "cherry")
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output
("apple", "banana", "cherry")
<class 'tuple'>#Example-7 x = range(6) #display x: print(x) #display the data type of x: print(type(x)) #Output range(0, 6) <class 'range'>
#Example-8
x = {"name" : "Rahul", "age" : 36}
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output
{"name" : "Rahul", "age" : 36}
<class 'dict'>#Example-9
x = {"ram", "gopal", "shyam"}
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output
{"ram", "gopal", "shyam"}
<class 'set'>#Example-10
x = frozenset({"ram", "gopal", "shyam"}
)
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output
frozenset({'apple', 'cherry', 'banana'})
<class 'frozenset'>#Example-11 x = True #display x: print(x) #display the data type of x: print(type(x)) #Output True <class 'bool'>
#Example-12 x = b"Hello" #display x: print(x) #display the data type of x: print(type(x)) #Output b'Hello' <class 'bytes'>
#Example-13 x = bytearray(5) #display x: print(x) #display the data type of x: print(type(x)) #Output bytearray(b'\x00\x00\x00\x00\x00') <class 'bytearray'>
#Example-14 x = memoryview(bytes(5)) #display x: print(x) #display the data type of x: print(type(x)) #Output <memory at 0x00B08FA0> <class 'memoryview'>
Below Examples is Set the Type And Print The Data Type:
If you want to specify the data type then you have to use following constructor.
#Example-1
x = str("Hello World")
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output
Hello World
<class 'str'>#Example-2 x = int(45) #display x: print(x) #display the data type of x: print(type(x)) #Output 45 <class 'int'>
#Example-3 x = float(20.5) #display x: print(x) #display the data type of x: print(type(x)) #Output: 20.5 <class 'float'>
#Example-4 x = complex(1j) #display x: print(x) #display the data type of x: print(type(x)) #Output: 1j <class 'complex'>
#Example-5
x = list(("ram", "gopal", "verma"))
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output:
["ram", "gopal", "verma"]
<class 'list'>#Example-6
x = tuple(("ram", "gopal", "verma"))
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output:
("ram", "gopal", "verma")
<class 'tuple'>#Example-7 x = range(6) #display x: print(x) #display the data type of x: print(type(x)) #Output range(0, 6) <class 'range'>
#Example-8
x = dict(name="John", age=36)
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output:
{'name': 'John', 'age': 36}
<class 'dict'>#Example-9
x = set(("ram", "gopal", "verma"))
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output
{"ram", "gopal", "verma"}
<class 'set'>#Example-10
x = frozenset(("apple", "banana", "cherry"))
#display x:
print(x)
#display the data type of x:
print(type(x))
#Output:
frozenset({'apple', 'cherry', 'banana'})
<class 'frozenset'>#Example-11 x = bool(5) #display x: print(x) #display the data type of x: print(type(x)) #Output True <class 'bool'>
#Example-12 x = bytes(5) #display x: print(x) #display the data type of x: print(type(x)) #Output: b'\x00\x00\x00\x00\x00' <class 'bytes'>
#Example-13 x = bytearray(5) #display x: print(x) #display the data type of x: print(type(x)) #Output bytearray(b'\x00\x00\x00\x00\x00') <class 'bytearray'>
#Example-14 x = memoryview(bytes(5)) #display x: print(x) #display the data type of x: print(type(x)) #Output: <memory at 0x00D58FA0> <class 'memoryview'>
