In this Python notes, you'll learn everything you need to start
programming in Python. This notes 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..
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!
