Using Python Functions As Classes

Published Mar 07, 2020Last updated Mar 08, 2020

In Python, you can use functions as classes. In py, everything is an object. How? I'm no py expert. Here's how we do it!

An Innocent Python Function

A function is like that

def devdotto():
    pass

and a class is like that:

class Car: 
    def __init__ (self): 
         self.wheel = 4 
         self.make = 'BWM' # i know
    def move(self): 
         print('moving')

more info:

make and wheels are attributes
while move is a method

some tests

car = Car() 
print(car.wheel)
print(car.make) 
car.move()

gives out

4
BWM
moving

Now Let Us Add Attributes

adding attributes to functions

devdotto.name = 'dev.to'
devdotto.users = 1123234

testing

print(devdotto.name)
print(devdotto.users)

gives out

dev.to
1123234

More Craziness: Adding Methods To Functions

adding an add method:

devdotto.add = lambda x,y: x+y

some info:

alt text

Testing

print(devdotto.add(1,2))

Gives out

3

Conclusion

Since some one liner libs make use of IEF (Immediately Executed Functions) using lambdas to compile even loops, these can be useful, but i can't think of any use cases (for using functions as classes), this said, this is one of py's party tricks, hence the cover image.
