def add(x, y):
return x + y
def do_twice(func, x, y):
return func(func(x, y), func(x, y))
a = 5
b = 10
print(do_twice(add, a, b))
Please explain step by step
Which is caller here?
Explain the 3rd and 4th line ?
why in 4th line we write add(add(x,y),add(x,y)) which is function of 1st line ?
how can we write function after return statement insted of (x+y+x+y )=30?

Isn't this just a reoccurring function called from within itself until a particular set of conditions are met? I don't know it just seems like shorthand to me. Like a do-while loop. I am sure it could be used for more than just factorials.
