Note: Using integer enum member values is a pretty common practice. That’s why the enum module provides an IntEnum to create enumerations with integer values directly. You’ll learn more about this class in the section called Exploring Other Enumeration Classes. The above example shows that cr...
By usingzip(), you can iterate throughfirst,second, andthirdat the same time. In theforloop, you assign the element fromfirsttoone, fromsecondtotwo, and fromthirdtothree. Then you print the three values. You can combinezip()andenumerate()by usingnestedargument unpacking: ...
