function prints the specified message to the screen, or other standard output device. The message can
be a string, or any other object, the object will be converted into a string before written to the screen.

3.5.4 Variables
Variables are containers used to store data values.
Creating a variable is very simple. You only need to name it and assign it a value. You don’t need to specify the data
type of the variable when assigning it, because the variable is a reference, and it accesses objects of different data types
through assignment.
Naming variables must follow the following rules:
• Variable names can only contain numbers, letters, and underscores
• The first character of the variable name must be a letter or underscore
• Variable names are case sensitive
Create Variable
There is no command for declaring variables in MicroPython. Variables are created when you assign a value to it for
the first time. It does not need to use any specific type declaration, and you can even change the type after setting the
variable.
x = 8 # x is of type int
x = "lily" # x is now of type str
print (x)
>>> %Run -c $EDITOR_CONTENT
