All language subtitles for 001python初学者教程概述

what's up everybody

in this video I'm going to teach you

everything you need to know to start coding with Python

I've also included 20

different hands on projects to help you learn

you can find

the entire list in the description of this video

our final project

will be a weather app

that fetches real time weather data from an API

even if you've never coded anything in your life before

I'll walk you through the basics

the ABCs of programming

if that sounds good to you

then I encourage you to sit back

relax and enjoy the show

this course doesn't cost you anything

but if you would like to help me out

you can help increase its reach by hitting the like

and subscribe if you'd like to be a fellow bro

thank you I appreciate it

I don't like boring introductions

so I say we just jump right in

there's two things we'll need to download

the first is a Python interpreter

to convert our written code to machine code

we're going to head to Python

org go to downloads

and download the latest version

we will open this executable

if you're on Windows you'll want to check this checkbox

add Python exe to path

and we will install now

the setup was successful

and that's all you need to do

to download the Python interpreter

the second download we'll need is an IDE

an integrated development environment

basically a place where we can write code for IDEs

there's two popular choices when writing pipe on code

Pie Charm and VS code

if you already use VS code you can stick with that

just be sure to download the Python extension

I find Pie Charm more beginner friendly

if you've never coded before

if you would like to use Pie Charm go tojetbrains

com Pie Charm

and we will click this green download button

there's two versions of Pie Charm

the professional version and the community version

the professional version is paid for

I would not recommend using it

only because there's plenty of free IDEs on the market

we'll use the Community Edition the free one

because I don't like to pay for things

and I'm sure you don't either

select the correct download for your operating system

I'm running Windows

I will download Pie Charm

we will open this executable

click next you could select a destination folder

I'll keep it as is

next I'll create a desktop shortcut

but you don't necessarily need to

click next

install

and we'll just have to give it a moment

okay the setup is now complete

I'll check this checkbox to run Pie Charm

when we close this window

after opening Pie Charm

we're going to create a new project

you can rename your Python project

I'll keep it as is

you can select a location

again I won't change that

you can create a sample welcome script

but for this tutorial we won't

let's select the latest Python version

and create our new project

in the menu to the left

we're going to create a new Python file file

new Python file

let's name this file main

but really you can name it anything

and select Python file

Python files end with the py file extension

we should have our main Python file

within our Python project folder

now we're going to print something

to the console window

within our main Python file

we're going to write a print statement

so type print

add a set of parentheses

between the set of parentheses

we will add a set of double quotes to print something

or single quotes

either one

my own preference is double quotes

normally in a programming tutorial

the instructor would tell you to print something

such as Hello World

but we like to be different here

instead think of your favorite food

in this case I like pizza

I will print I like pizza

to run our Python program

we will click the screen arrow

to run our main Python file

we should have a console window

that displays our output

I like pizza or whatever your favorite food is

let's print another line of code

let's print

it's really good

by adding a second print statement

we are printing a second line of code

now we'll discuss comments

the Python interpreter doesn't output comments

to write a comment

you use a pound sign

I like to call this a hashtag

my comment will be this is my first

Python program

comments are used as notes for yourself

or for other people reading this code

if I were to run this code again

this comment is not displayed to the output

we still have I like pizza

it's really good

alright everybody

so that is your very first Python program

and in the next topic we'll discuss variables
