Vanishing Elements

The function remove_negatives(numbers) should return a list with all negative numbers removed.

It seems to work for some inputs, but with others some negatives survive even though the code clearly checks every element.

This is a particularly nasty bug — the code looks completely correct. The logic is right. Yet the output is wrong.

solution

Read the code. Before running anything: what does the last line below give?

def remove_negatives(numbers):

for n in numbers:

if n < 0:

numbers.remove(n)

return numbers

>>> remove_negatives([-1, -2, 3])
