An assignment statement creates a new variable and gives it a value:
>>> message = 'And now for something completely different' >>> n = 17 >>> pi = 3.1415926535897932
This example makes three assignments. The first assigns a string to a new variable named message
; the second gives the integer 17
to n
; the third assigns the (approximate) value of \(\pi\) to pi
.
A common way to represent variables on paper is to write the name with an arrow pointing to its value. This kind of figure is called a state diagram because it shows what state each of the variables is in (think of it as the variable’s state of mind). Figure \(\PageIndex{1}\) shows the result of the previous example.
