I am working on the file "016 - Yak Shaving/func_py/func_py.ipynb".
The first task is:
What can act as a function in Python?

A function object, created with the def statement.
A lambda anonymous function, restricted to an expression in single line.
An instance of a class implementing the __call__ function.
Can you write Python code for it?

#Here can act as a function in Python.

def min_def(x, y):
    return x if x < y else y

min_lambda = lambda x, y: x if x < y else y

class MinClass:
    def __call__(self, x, y):
        return x if x < y else y

min_class = MinClass()
print(min_def(2,3) == min_lambda(2, 3) == min_class(2,3))
