That raises my next question. Under what sort of programming circumstances
does it make sense?
"It" being object oriented programming.
OO is good for encapsulation and code-reuse. One good sign you should
consider a class is if you start building up many global variables.
Instead of:
spam = 1
ham = 2
eggs = 3
def cook_spam():
pass
def slice_ham():
pass
def scramble_eggs():
pass
there may be something to say for putting those related functions into a
class:
class Breakfast:
spam = 1
ham = 2
eggs = 3
def cook_spam(self):
pass
def slice_ham(self):
pass
def scramble_eggs(self):
pass
This then allows you to have two Breakfasts, each one of which could
modify their own copies of spam, ham and eggs without effecting the other.
