Variable assignment

Variables are used to store values that can be used later in your code. Think of a variable as a container that holds a value. You can give a variable any name you want, as long as it follows certain rules.

To assign a value to a variable, you use the equals sign (=). Here's an example:

my_variable = 10
print(my_variable)  # output: 10

In this example, we created a variable called my_variable and assigned it the value of 10. Now, whenever we refer to my_variable in our code, it will have the value of 10.

You can also assign different types of values to variables. For example, you can assign a string (a sequence of characters) to a variable:

my_name = "John"
print(my_name)  # output: John

In this case, my_name is a variable that holds the value "John". You can use this variable later in your code to refer to the string "John".

You can also assign the result of an expression to a variable. For example:

x = 5 + 3
print(x)  # output: 8

In this case, x is a variable that holds the value 8, which is the result of the expression 5 + 3.

Variables can be changed or updated throughout your code. You can assign a new value to a variable by simply using the equals sign again:

x = 10
x = x + 5
print(x)  # output: 15

In this example, we first assign the value 10 to x. Then, we update x by adding 5 to its current value. After this code runs, x will have the value 15.

Remember, when you assign a value to a variable, you can use that variable later in your code to refer to the value. This allows us to store and manipulate data in your programs.
