Python for Beginners - Learn Python in 1 Hour
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.

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:
name = input("What is your name? ")print("Hello, " +
name)
When we run this program, it will prompt the user to input their name. Once a
value is entered, the program will print the greeting message with the input
value.
Data Types in Python
There are three main data types in Python: numbers, strings, and booleans.
Numbers - This includes integers and floating-point numbers.
Strings - This includes textual data.
Booleans - This includes True and False values.
