format(SetX, SetY, SetZ)) and press Enter. You see one set printed on each line, 

like this:

{'Blue', 'Orange', 'Red', 'Green', 'Black', 'Yellow'}

{'Green', 'Black'}

{'Blue', 'Red'}

The outputs show the results of the math operations: 

union()

, 

intersection()

, 

and 

difference()

. Python’s fancier print formatting can be useful in working 

with collections such as sets. The 

format()

 function tells Python which objects to 

place within each of the placeholders in the string. A placeholder is a set of curly 

brackets ({}) with an optional number in it. The escape character (essentially a kind 

of control or special character), 

/n

, provides a newline character between entries. 

You can read more about fancy formatting at

.

You can also test relationships between the various sets. For example, type SetA.
