You can get the data type of any object by using the ____________ function:
type()
Example:
Print the data type of the variable x:
x = 5
print(type(x))
Get the Output and the Data Type:
x = “Hello World”
display x:
Code:
x = “Hello World”
print(x)
print(type(x))
Output:
Hello World
<class ‘str’>
Get the Output and the Data Type:
x = 20
display x:
Code:
x = 20
print(x)
print(type(x))
Output:
20
<class ‘int’>
Get the Output and the Data Type:
x = 20.5
display x:
Code:
x = 20.5
print(x)
print(type(x))
Output:
20.5
<class ‘float’>
Get the Output and the Data Type:
x = 1j
display x:
Code:
x = 1j
print(x)
print(type(x))
Output:
lj
<class ‘complex’>
Get the Output and the Data Type:
x = [“apple”, “banana”, “cherry”]
display x:
Code:
x = [“apple”, “banana”, “cherry”]
print(x)
print(type(x))
Output:
[‘apple’, ‘banana’, ‘cherry’]
<class ‘list’>
Get the Output and the Data Type:
x = (“apple”, “banana”, “cherry”)
display x:
Code:
x = (“apple”, “banana”, “cherry”)
print(x)
print(type(x))
Output:
(‘apple’, ‘banana’, ‘cherry’)
<class ‘tuple’>
Get the Output and the Data Type:
x = range(6)
display x:
Code:
x = range(6)
print(x)
print(type(x))
Output:
range(0, 6)
<class ‘range’>
Get the Output and the Data Type:
x = {“name” : “John”, “age” : 36}
display x:
Code:
x = {“name” : “John”, “age” : 36}
print(x)
print(type(x))
Output:
{‘name’: ‘John’, ‘age’: 36}
<class ‘dict’>
Get the Output and the Data Type:
x = {“apple”, “banana”, “cherry”}
display x:
Code:
x = {“apple”, “banana”, “cherry”}
print(x)
print(type(x))
Output:
{‘apple’, ‘cherry’, ‘banana’}
<class ‘set’>
Get the Output and the Data Type:
x = frozenset({“apple”, “banana”, “cherry”})
display x:
Code:
x = frozenset({“apple”, “banana”, “cherry”})
print(x)
print(type(x))
Output:
frozenset({‘apple’, ‘banana’, ‘cherry’})
<class ‘frozenset’>
Get the Output and the Data Type:
x = True
display x:
Code:
x = True
print(x)
print(type(x))
Output:
True
<class ‘bool’>
Get the Output and the Data Type:
x = b”Hello”
display x:
Code:
x = b”Hello”
print(x)
print(type(x))
Output:
b’Hello’
<class ‘bytes’>
Get the Output and the Data Type:
x = bytearray(5)
display x:
Code:
x = bytearray(5)
print(x)
print(type(x))
Output:
bytearray(b’\x00\x00\x00\x00\x00’)
<class ‘bytearray’>
Get the Output and the Data Type:
x = memoryview(bytes(5))
display x:
Code:
x = memoryview(bytes(5))
print(x)
print(type(x))
Output:
<memory at 0x0368AFA0>
<class ‘memoryview’>
Get the Output and the Data Type:
x = None
display x:
Code:
x = None
print(x)
print(type(x))
Output:
None
<class ‘NoneType’>
If you want to specify the data type, you can use ______________ functions.
constructor
If you want to specify the data type, you can use constructor functions. Give the 14 examples and then after it give the sample code on how to generate the output.
display x:
x = str(“Hello World”)
x = int(20)
x = float(20.5)
x = complex(1j)
x = list((“apple”, “banana”, “cherry”))
x = tuple((“apple”, “banana”, “cherry”))
x = range(6)
x = dict(name=”John”, age=36)
x = set((“apple”, “banana”, “cherry”))
x = frozenset((“apple”, “banana”, “cherry”))
x = bool(5)
x = bytes(5)
x = bytearray(5)
x = memoryview(bytes(5))
Sample Code:
x = str(“Hello World”)
print(x)
print(type(x))
Output:
Hello World
<class ‘str’>
