Python for Beginners Learn Python 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 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 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 Converting Data Types in Python Python has several built in functions for converting the types of our variables For example we have the int function for converting a value to an integer birth year 1982 age 2020 int birth year print You are str age years old In the above example we use the int function to convert the birth year string to an integer so we can subtract it from the current year We also have the float function for converting a value to a float num 10 5 float num float num print float num In the above example we use the float function to convert the num string to a floating point number
