INTRODUCTION TO PYTHON
We'll start by talking about variables. In programming, a variable is
a named location used to store data in memory. It is called a
variable because its value can vary throughout the execution of a
program. Variables must be given unique names, called identifiers.
In Python, variable names are case sensitive and cannot start with
a number. They can contain letters, numbers, and underscores.
For example, let's say we want to store the number of apples I have
in a variable named apples. We can do this with the following
code:
Apples = 5
Now, apples is a variable that stores the value 5. We can use this
variable in calculations, such as adding more apples:
apples = apples + 3
print(apples)
This will output 8, because we added 3 to the value stored in
the apples variable.
Next, let's talk about data types. A data type is an attribute that tells
what kind of data a particular variable can hold. There are several
basic data types in Python, including int, float, str, and bool.
