Variables, Data Types and Operators

In Python, variables are used to store values, and data types define the type of values that can be stored in variables. Operators are used to perform operations on variables and values. Here's a brief explanation of these concepts in Python, along with examples:

1. Variables: Variables are used to store values in Python. To assign a value to a variable, use the assignment operator =. For example:

makefile
Copy code
x = 10
y = 20
z = x + y
print(z)
Copy

This code assigns the value 10 to the variable x, the value 20 to the variable y, and the sum of x and y to the variable z. When the code is executed, it will print the value 30.

1. Data Types: Data types define the type of values that can be stored in variables. Some common data types in Python include:

• Integer (int): Whole numbers, such as -1, 0, 1, 2, etc.
• Float: Real numbers, such as 3.14, -0.1, etc.
• String (str): Sequences of characters, such as "hello", "world", etc.
• Boolean (bool): Logical values, either True or False.

For example:

makefile
Copy code
x = 10      # integer
y = 3.14    # float
z = "hello" # string
w = True    # boolean
Copy

1. Operators: Operators are used to perform operations on variables and values. Some common operators in Python include:

• Arithmetic operators: +, -, *, /, %, ** (for addition, subtraction, multiplication, division, modulo, and exponentiation, respectively)
• Comparison operators: ==, !=, <, >, <=, >= (for equality, inequality, less than, greater than, less than or equal to, and greater than or equal to, respectively)
• Logical operators: and, or, not (for logical AND, logical OR, and logical NOT, respectively)

For example:

makefile
Copy code
x = 10
y = 20
z = x + y
print(z) # 30

a = 30
b = 40
c = a > b
print(c) # False

d = True
e = False
f = not e
print(f) # True
Copy

This is a brief overview of variables, data types, and operators in Python. By understanding these concepts, you'll be able to write more powerful and flexible code in Python.
