Distance formula between two points in a list

Question

I need to take a list I have created and find the closest two points and print them out. How can I go about comparing each point in the list?

There isn\'t any need to pl

Answer 1

First, some notes:

a**2 # squares a
(xi - xii)**2 # squares the expression in parentheses.

mInput doesn't need to be declared in advance.
fList.append((x, y)) is more pythonic than using +=.

Now you have fList. Your distance function can be rewritten to take 2 2-tuple (point) arguments, which I won't bother with here.

Then you can just write:

shortest = float('inf')
for pair in itertools.combinations(fList, 2):
    shortest = min(shortest, distance(*pair))
