Data types are one of the building blocks of python. And You can do a lot of things with data types! Fact: In python, all data types are implemented as an object. A data type is like a specification of what kind of data we would like to store in memory and python has some built-in data types in these categories: 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 Now, let's demistify all these data types by using function to display the data type of the variable. type() Text type str stands for a string in python used for storing text in python. Strings can be written either in single quotes or double quotes in python, hence your choice. str Example: Output: Hello, world!
<class 'str'> Numeric types int stands for integer used to store integers (positive and negative numbers). int Example: Output: 4
<class 'int'> float stands for floating-point numbers (decimal point numbers). float Example: Output: 3.14
<class 'float'> complex numbers have a real and imaginary part, which are each a floating-point number. Complex numbers can be written in two forms: real + (imag)j complex(real, imag) complex Example: Output: (5+10j)
<class 'complex'> Sequence types list A is data type where you can store a collection of data. A list can also contain different data types. A list is and and list ordered changeable allows duplicate members. Example: Output: ['Captain America', 'Iron Man', 'Thor', 'Hulk', 'Black Widow', 'Hawkeye']
<class 'list'> tuple A is data type where you can store a collection of data. A tuple can also contain different data types. A tuple is and and tuple ordered unchangeable allows duplicate members. Example: Output: ('Captain America', 'Iron Man', 'Thor', 'Hulk', 'Black Widow', 'Hawkeye')
<class 'tuple'> range The type represents an immutable (unchangeable) sequence of numbers. Commonly used for looping a specific number of times in for loops. range Example: Output: range(0, 10)
<class 'range'> Mapping type dict stands for dictionary in python. Dictionaries are used to store data values in key: value pairs. A dictionary is a collection which is , and dict unordered changeable does not allow duplicates. Example: Output: {'Learning': 'Programming', 'Language': 'Python', 'Day': 4}
<class 'dict'> Set types set A is data type where you can store a collection of data. A set can also contain different data types. A set is and and set unordered unindexed allows no duplicate members. Example: Output: {'Black Widow', 'Iron Man', 'Thor', 'Hawkeye', 'Hulk', 'Captain America'}
<class 'set'> frozenset data type can be created by function. The function accepts an iterable and returns an unchangeable frozenset object (which is like a set object, only unchangeable). frozenset frozenset() frozenset() Example: Output: frozenset({'cherry', 'banana', 'apple'})
<class 'frozenset'> Boolean type bool stands for boolean in python. Booleans represent one of two values: True or False. bool Example: Output: True
<class 'bool'>
False
<class 'bool'> Binary types bytes data type can be created in two forms: function prefix 'b' bytes bytes() Example: Output: b'hello'
<class 'bytes'>
b'Hello'
<class 'bytes'> bytearray function returns a bytearray object. It can convert objects into bytearray objects. bytearray() Example: Output: bytearray(b'\x00\x00\x00\x00')
<class 'bytearray'> memoryview function returns a memory view object from a specified object. memoryview() Example: Output: <memory at 0x2b4f7a8a7408>
<class 'memoryview'> Note As you might have observed earlier, some data types can be also implemented using their constructors. This same technique can also be applied to every data type. Example: Output: Hello, World!
