Hi! I’m on Python (something pretty new for me).

On functions, I’m trying to figure out what “return” does. For example

def biggest_number(*args):
print max(args)
return max(args) -----------> here

What does it do?

Thanks!

have you checked with FAQ:

hi! I’m not sure why this doesn’t work, can anyone tell me?

Hi,

With the code in this exercise, I tried to make the script receive input from the console, but it returns ‘Unicode’ as the type. The function works fine if you pass the argument from code, but do I need to define/transform the raw_input to make it work?

Here is my code:

x = raw_input("Enter a number: ")

print type(1)
print type(1.0)
print type(x)

print distance_from_zero(x)

def distance_from_zero(x):
if type(x) == type(1) or type(x) == type(1.0):
return abs(x)
else:
return “Nope”

print distance_from_zero(-6)
print distance_from_zero(-56.983)
print distance_from_zero(“Abc”)

same problem :confused:

please see this topic:

Asking better questions will get better response.

I guess it was fixed, because it now works two years later.

#13

I’m trying to do something similar, and I think the problem is that raw_input() always outputs a string.
I tried using x = int(rawinput("Enter a number: ") to transform the input to an integer, which works if the user types an integer, but fails if they type a float or a string.

#14

Do you still have a question, or?

#15

Not really, just adding information to @stephenmak5974281141 question.
I assume that if you want to use raw_input() for this exercise, you need to check the input somehow before accepting it to the function?

#16

or you could write a separate function which validates the input.
