Got it. I just wanted to make sure I get a better understanding of how
to use any() and all() even though I already had a solution at hand.
So far, I worked through 24 out of 68 built-in functions

Hej there,
I use any() and all() frequently. For example, suppose you have a
function that takes a list of numbers, and they are all supposed to be
positive.
def calculate_values(numbers):
if all(number 0 for number in numbers):
# do the calculation
else:

BUT: this really doesn't make much sense! Your if construct is a lot more
readable than what any or all would give you in this example.
As pointed out repeatedly here, you can always replace any() and all() with
a combination of for and if, it's really a question of readability (and
style)

Hey there,
I am currently looking into all built in functions in Python 3.3.0,
one by one, in order to understand what each of them specifically does
(I am familiar with some of them already, but most built in functions
are still alien to me). I am working with the Python documentation

In my experience they aren't used all that often. But the logic is

Actually the last one surprised me. I expected false. So maybe a resident
guru can explain that anomaly... I assume it works on the basis of testing
until it finds a false and so an empty sequence
always returns true...
The term you're thinking of is vacuous truth

I'm new to python and I was wondering if you could tell me how I would:
first, define a function,distance_from_zero, with one parameter (choose any
parameter name you like).
Second, have that function do the following:
1. Check the type of the input it receives.
2. If the type
