Python Language - Python Full Course
for Beginners
Programming with Talha
I am a software engineer with two decades of experience
and I've taught over 3 thousand people how to code. I have
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means it's no longer maintained or supported.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 going 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.
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 doesn't know what to do
, with subtraction. So whenever you see this message, that
means there is something wrong with your program.
Python doesn'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 don'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.
