Adding a character between the whitespaces of a multiple word string

Question

I'm trying to make a function that takes in an undetermined amount of parameters, which are the words, that will add a "+" between the single words. At the end it should still be a string.

def add_words(word1 word2 word3 ...)

output:

"word1+word2+word3 ...")

You can use the .join() method of strings and argument expansion to do this!

def add_words(*words):
    return "+".join(words)

>>> add_words("foo", "bar", "baz")
'foo+bar+baz'

Note that the .join() method is actually being used from the string "+", rather than the argument words

It's a bit different from what I wanted to do but still helped me out. I didn't have the words split up in different stings and just had a full sentence so I wrote a function for that and then used your solution. Thanks for helping me!

Excellent! If you already have some char and not a collection, you may be able to replace 'em directly with .replace() or a regex, or speculating, perhaps you're really looking for URL encoding docs.python.org/3/library/… (which will handle special characters too)
