Python Python Basics Functions and Looping Functions

"Create a function" practice exercise This is what I was asked to do, but I can't figure out if I'm on the right track.

Challenge Task 1 of 1 Let's create a function that determines if a specific value is odd.

Let's name the function is_odd and have it declare a single parameter.

It should return True if the value is not divisible by 2.

Here is a link to my code in workspaces:


open up the 'create_a_function.py' file

I still cannot get this, can you help?

Thank you

You have the general idea. There are some syntax issues to clean up:

def is_odd(number,2):  # do not need to pass in constant, remove ", 2"
    if 0 = (number % 2)  # if needs trailing colon (:), compare uses double equal (==)
        print("False")  # should return False, not print it
    elif 1 <= (number % 2):  # a condition uses 'elif', without condition use 'else'
        print("True")  # should return True, not print it

Running the fixed code in the REPL:

$ python
Python 3.6.3 (default, Oct  3 2017, 21:45:48) 
[GCC 7.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> def is_odd(number):
...     # your fixed code here
...     pass
>>> is_odd(4)
>>> is_odd(5)

Post back if you need more help. Good luck!!

Thanks Chris! That was very helpful!
