Getting Started

To get started with Python, you will need to download and install the Python interpreter. You can download the Python interpreter from the official Python website.

1. Once you have downloaded and installed the Python interpreter, you can open a terminal window and type the following command to start the Python interpreter:

python

2. The Python interpreter will now be running and you can start typing Python code.

Your First Python Program

Your first Python program will print the message "Hello, world!" to the console. Here is the code for this program:

print("Hello, world!")

To run this program, type the following command into the Python interpreter:

python hello_world.py

The Python interpreter will now run the program and print the message "Hello, world!" to the console.

Variables

Variables are used to store data in Python. You can create a variable by assigning it a value.

my_name = "John Doe"

You can then use the variable to access the data.

print("My name is", my_name)

Data Types

Data types define the type of data that a variable can hold. Python has several built-in data types, including:

• int: Integer
• float: Floating-point number
• str: String
• bool: Boolean

You can check the data type of a variable using the type() function.

print(type(my_name))

Operators

Operators are used to perform operations on data. Python has a variety of operators, including:

• + : Addition
• - : Subtraction
• * : Multiplication
• / : Division
• % : Modulus

You can use operators to perform calculations on data.

result = 10 + 20 print(result)

Control Flow

Control flow statements are used to control the flow of execution of a program. Python has several control flow statements, including:

• if: If statement
• elif: Elif statement
• else: Else statement
• for: For loop
• while: While loop

You can use control flow statements to make decisions and repeat code.

if result > 10: print("The result is greater than 10")

Functions

Functions are used to group code together and perform a specific task. You can define a function using the def keyword.

def greet(name): print("Hello", name)

You can then call the function to execute the code.

greet("John Doe")

Classes

Classes are used to create objects. You can define a class using the class keyword

class Person: def __init__(self, name): self.name = name def greet(self): print("Hello", self.name)

You can then create an object of the class.

john = Person("John Doe") john.greet()
