In this article, we'll go over the basics of how to use Python, from installing it on your computer to writing your first program.
Installing Python
The first step to using Python is to download and install it on your computer. Python is available for free on the official Python website, and it works on Windows, Mac, and Linux operating systems.
To download Python, go to the Python website and click on the "Downloads" link. Then, choose the version of Python you want to download, and follow the installation instructions.
Writing Your First Python Program
Once you have Python installed on your computer, you're ready to start writing Python programs. Open up a text editor, like Notepad or Sublime Text, and type in the following code:
print("Hello, World!")
Save the file as hello.py. The .py extension tells your computer that this is a Python program. Now, open up your computer's terminal or command prompt, navigate to the directory where you saved the hello.py file, and type in the following command:
python hello.py
This will run your Python program, and you should see the message "Hello, World!" printed out on your screen.
Variables and Data Types
In Python, you can assign values to variables using the = symbol. For example, you can create a variable called name and assign it the value "John" like this:
name = "John"
Python has several built-in data types, including integers, floats, strings, and booleans. You can use these data types to store and manipulate different kinds of information. For example, you can create an integer variable called age and assign it the value 20 like this:
age = 20
Conditional Statements and Loops
Conditional statements and loops are important programming concepts that allow you to control the flow of your program. In Python, you can use the if statement to test a condition and execute different code depending on the result. For example:
if age >= 18:
print("You are an adult.")
else:
print("You are a minor.")
You can also use loops to repeat a block of code multiple times. The most common loop in Python is the for loop, which allows you to iterate over a sequence of values. For example:
for i in range(5):
print(i)
Cookie time!
