Write closures with Python
It is not the easiest bit to grasp, but really worth it.
A closure is a function that returns a function.
def multiplier_of(x): def multiply(y): return x * y return multiply multiplywith5 = multiplier_of(5) # multiplywith5 is equal to: # # def multiply(y): # return 5 * y # print(multiplywith5(9)) # => 45
In Rubyland one usually uses blocks (yield) instead of closures.
