Python Tutorial - Python Full Course for
Beginners
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 It 's considered legacy which means it 's no longer maintained or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 preparing for online
python tests or college exams. So with this syntax , you can
basically copy or clone a string. So once again the square bracket.
brackets syntax works , we can also use a similar syntax to extract a
few characters instead of 1 character. In this tutorial, we 're going to
look at formatted strings in Python programming language.
Formatted strings are particularly useful in situations where you
dynamically generate some text with your variables. Let 's say we
want to print this on the terminal. So I 'm going to run this program
there you go. This is what we get.
Jon Smith is a coder. So to define formatted strings , prefix your
strings with an F and then use curly braces to dynamically insert
values into your strings. This is particularly useful when you receive
