Python | Lesson 1 | Data Types

Python Indentation

    Python uses indentation to indicate a block of code.

    Indentation is the spaces at the beginning of a code line.

        Example:

        if 10 > 3:

             print("10 is greater than 3)

Comments:

    Comments start with #

       

        Example:  # This is a Python Comment

                print("Comments ignored")

Variables:

    Variables stores the data value

    Example:

            i = 10

            print (i)

Global Variables:

    Variables created outside of the Function are global variables

    Example:

        a = "global"

        def newFunction():

            print("a is " + a)

        newFunction()

Data Types:

    Text:   str

    Numeric:    int, float, complex

    Sequence:   list, tuple, range

    Mapping:    dict

    Set:    set, frozenset

    Boolean:    bool

    Binary: bytes, bytearray, memoryview

    None:   NoneType

Casting:

    use primitive types to cast the variables

    Example:

        a = int(1)  

        b = int(4.3)
