Question

I should write a function min_in_list(munbers), which takes a list of
numbers and returns the smallest one. NOTE: built-in function min is NOT allowed!

def min_in_list(numbers):
    the_smallest = [n for n in numbers if n < n+1]
    return the_smallest

What’s wrong?

Answer 1

def min_of_two(x, y):
    if x >= y: return x
    else: return y

def min_in_list(numbers):
    return reduce(min_of_two, numbers)

You have to produce 1 number from list, not just another list. And this is work for reduce function (of course, you can implement it without reduce, but by analogy with it).
