Exercism 2Fer

python_exercism2-fer.py

def two_fer(name = ''):# siting default argument as ''
    #name!=''?print('One for '+name+',one for me'):print('One for you , one for me');
    if name!='':
        #print('One for',name,', one for me')
       # print(f"One for {name}, one for me")
       f"One for {name}, one for me"
    else:
        f"One for you, one for me"
       #print('One for you , one for me')

The purpose of this exercise was to return a string so you need to use the keyword return followed by the string. Ex.: return f"One for {name}, one for me".

The difference between strings and f-strings is that f-strings change the followed pattern {variable} by the respective variable. What I want to say is that there was no need to use f"One for you, one for me" since you aren't using any variable. You could simply use a string.

In my opinion the best approach to this exercise would be:

def two_fer(name = 'you'):
    return f'One for {name}, one for me'

But pay attention that in this case if you call the function passing '' (empty string) as argument it will return 'One for , one for me'. However, your code will return 'One for you, one for me'. This happens because an empty string is an object so it doesn't trigger the default argument. This is ambiguous and depends on what the programmer wants.

One last thing. Please don't mix both "" and ''. Stick with one.
