Python Tutorial - Python Full Course for
Beginners
Programming with Mosh
Mosh is a software engineer with two decades of experience and I
've taught over 3 million people how to code. He has designed
this Python course for anyone who wants to learn Python. In this
tutorial I 'm going to show you how to download and install
Python on your computer. You will learn how to use Python in
machine learning or artificial intelligence. All the materials you
're going to learn in this course will apply to the latest version of
Python as well. At the time of recording this video the latest.
version is python 3. 7. 2. Chances are in the future , when you
are watching this tutorial there is a newer version of. Python
available. The first time we run pycharm we 're going to get this
warning because this is an application that we download from the
internet. So let 's go ahead and open it every time you open it,
click on create new project. Make sure that base interpreter is set
to Python 3. Mac computers come with an older installation of
Python, that 's Python 2. It 's considered legacy which means it 's
no longer maintained or supported. So by convention, all Python
files should have this py extension.
In this Python tutorial , we 're gong to take this program to the
next level and make it more interesting. So I 'm going to show
you how to draw a dog hair. As part of this tutorial you will learn
how Python code gets executed and you will also learn about a
few programming terms. In the future as you learn more Python
you 'll be able to build applications that have a graphical user
interface. With this piece of code we can draw 10 asterisks on the
terminal. Python interpreter tries to execute line 4 when it
executes line 4. It will evaluate the code that we put in between
parenthesis. and before the parenthesis , add a space , once
again , add an asterisk , space , 10. So let 's run this program one
more time , there you go. Are you excited to learn Python and get
started on this career path ? If you are, I would encourage you to
make a commitment and spend 2 hours every day practicing
python. Use the comment box below and let me know why you
, are learning Python , what do you want to do with it ? What 's
your dream job ? I would love to hear your story.
Python interpreter executes our code line by line from the top. On
the second line we can update the value of this price variable , so
we can reset it to a new value like 20. On line 2, we can define
another variable called rating and set it to number 4. 9. Now note
that Python is a case sensitive language. Python is sensitive to
lower case and upper case letters. In this tutorial, I 'm going to
show you how to receive input from the user. So we 're going to
write a small program that asks the user 's name and then we 'll
print a greeting message customized for that user. In Python we
also have functions for common tasks such as printing messages,
receiving input , and so on. Mosh has created a cheat sheet with
summary notes to review the materials in this course. The link is
below this video. So I have done my best to create the best
possible Python course on Youtube. And I really appreciate it if
you support my hard work by liking this video and sharing it with
others.
We 're going to write a program that will ask the year that we
were born in and then it will calculate our age and print it on the
terminal. Python does n't know what to do with subtraction. So
whenever you see this message , that means there is something
wrong with your program. Python does n't know how to interpret
or how to evaluate this expression. To fix this problem we need to
convert this 1982 into an integer and then we 'll be able to
subtract it from 2019 and that is easy. I want you to write a
program ask the user their weight and then convert it to
kilograms. In this tutorial, you 're going to learn more about
Python strings. So I 've defined this course variable and set it to
Python for beginners. defined another variable weight_kg we set
this to weight_lbs times 0. 45. And finally let 's print weight
underline kg. Let 's run this Python program and see what
happens.
We use square brackets to get a character and a given index in
this string. The index of the first character in the string is 0. We
can also use a negative index here. This is one of the features
that we do n't have in other programming languages as far as I
know. The square bracket syntax is pretty important if you 're
