Python Programming Tutorial
In this Python tutorial, you'll learn everything you need to start programming in Python. This tutorial is
perfect for data science, machine learning, and web development. No prior knowledge in Python or
programming is required as everything will be taught from scratch. I'm Mosh Hamadani, and I've taught
millions of people how to code through this channel. If you're new here, make sure to subscribe as I
upload new videos every week. Let's jump in and get started.
What is Python?
Python is a multipurpose programming language that can be used for a variety of different tasks, such as
automation, web development, and data science.
• You can use Python in automation to automate repetitive tasks and save time and increase
productivity.
• You need to install a code editor to write your own Python code.
• You can build amazing websites powered by Python.
We'll be using PyCharm as our code editor in this tutorial. When you open PyCharm for the first time,
you have to configure a few settings, but we can skip that for now and set defaults. Let's create a new
project and collapse the project window to give more space. We can then print a message on our
application window.
Running Python Code
To run Python code in PyCharm, we go to the run menu and select run, or use the shortcut (ctrl+shift+r
on a Mac). Then select the app to run, and the output will appear in the terminal window. Python is case
sensitive so make sure to use the correct case when coding. We can declare variables, such as age and
price, and assign them values. Python also has boolean values that can be true or false.
Now let's start coding!
age = 30
print(age)
price = 19.95
print(price)
Declare and Use Variables in Python
Here's a little exercise for you: imagine we want to write a program for a hospital, so we're going to
check in a patient named John Smith. He's 20 years old and is a new patient. I want you to declare a few
variables to store these values.
Use the comment section below to share your code.
Receiving User Input in Python
In Python, we have a built-in function called input() that we use to read a value from the terminal
window. We can add a string argument to the function to prompt the user for input.
Let's write a simple program to demonstrate this:
