I am given a list of integers/floats and I need to find the two numbers closest together. How would I do that using only nested for loops?
For each element, you have to compare the distance of it to each of the other elements with your previous "closest" value - any time this comparison yields smaller values, you remember that pair as the "two closest" ones.
So, it is straightforward:
def find_two_closest(numbers): # most distant points: delta = max(numbers), min(numbers) for i, element in enumerate(numbers): for j, sec_element in enumerate(numbers): if i == j: continue if abs(sec_element - element) < abs(delta - delta): delta = sec_element, element return delta
