I'm trying to store the replace function in a method to make it easier to read and work with.

Basically instead of doing str.replace(string, ' ', '_').lower() I'd prefer doing replaceandlower(string). I'm doing this to format a title to a slug (like "How's the weather today" becomes --> "hows_the_weather_today").

At this moment I have:

def replaceandlower(string):
  str.replace(string, ' ', '-').lower()

I thought that the following would work but it returns a None object type:

url = replaceandlower(title)

What I'm doing wrong?

You need to add a return:

def replace_lower(string):
    return string.replace(' ', '-').lower()  # Fixed the syntax for this also.

at the moment you are not actually giving anything from the function, this is equivalent to returning None.
