Learn Python Programming - 5 - Variables

We will discover what are variables in this video. How is data stored into variables and then how you can retrieve it later for easier access. We will look at all this through a visualization using the Turtle library from Python. ...

I would just like to thank you for making these videos. So many tutorials out there assume you know all the terminology and just sling things around expecting you to know what the terms are, what they mean, and how they're used. So the tutorial just shows you how to make something ---That's cool and all, but in order for me to completely understand how to build my own code I need to know why a term means what it does, and how it's used.

So many programming tutorials feel like someone teaching me how to cook a dish and what ingredients to use, but instead of saying to me "use 1 cup of sugar to add sweetness" they say "use 236.59 ml of azúcar granulado to agregar dulce" - That's fine and all, but they're speaking a different language than I speak. I can copy what they say all I want, and spit it out, but that won't get me any closer to actually forming my own sentences and understanding what I just said, even though the program I just spoke to understands.

You do a great job using analogies to put in our minds what each word in programming means in relation to our own day-to-day language. That way, we can actually think about what we want to say (to whatever program will be using our script) and understand why we say it that way so that we can use it properly.

Thanks for that! :D

this is quite nice-
import turtle
t=turtle.Turtle()
z=0
x=100
y=20
while z<18:
t.left(y)
t.circle(x)
z+=1

Why does not your page have a login/sign up section?
Every time I try to enter the profile, its creating problems for logging in as it continously sends me verification messages only

[abhijeetkumarbarman]

a = 'apple'
b = 'banana'
m = 'mango'
print(a)
print(m)
print(b, a)
c = (45/5+2-8*57)
d = (65*37/25-100+10)
print(a)
print(b)
print((m))
print(c)
print(d)

You declared this at the beginning my_turtle= turtle.Turtle()-- what is this called ?

I didn't notice this first and started writing like this-- my_turtle= turtle.forward(100)
and it worked unknowingly.

So, what is the importance of first thing you declared ?

Hi cleaver, i have a question.Why when y put my_turtle.rigth(90) it tells me this:Traceback (most recent call last):
File "D:/Exercice Python.py", line 7, in <module>
my_turtle.rigth(90)
AttributeError: 'Turtle' object has no attribute 'rigth'

[allisonnnmarie]

Why do you need the “my.turtle = turtle.Turtle()” ? What does this do?

[ronwillis]

Using Python 3.

>>> import turtle
>>>
>>> my_turtle = turtle.Turtle()
>>> my_turtle.forward(100)
>>> my_turtle.left(90)
>>> my_turtle.forward(100)
>>> my_turtle.left(90)
>>> my_turtle.forward(100)
>>> my_turtle.left(90)
>>> my_turtle.forward(100)

Hi.I have a question:how can you have the option to introduce the value of a variable manually after running the programe?(for example, in c++ if you want to introduce the value for a variable("x")we write the code:"cin>>x;", which allows you to introduce any value you want).How can I do that in Phyton?

[nszpwzg]

I figured it out right at 0:46 right after I saw the code.

[kyranbrockett]

so then is my_turtle = turtle.Turtle() a variable??
