How to I detect if each number in the list is equal to or below zero?

Question

I have -1 as each element in the list but it still prints "there is a positive"

Thanks in advance,

WG

Answer 1

all() checks if all items in an array are True, then returns a boolean. To check if a number is less than zero in the list, you can do: all([i>=0 for i in [-1,-2,-3,3]])

Answer 2

I would just do

if max(test_3) <= 0:
    print("all negative")
else:
    print("there is a positive")

This seems more explicit to me that you want the maximum value to be 0 or less
