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! – Celltox Jan 22 '21 at 17:16

    Excellent! If you already have some char and not a collection, you may be able to replace 'em directly with [`.replace()` or a regex](https://stackoverflow.com/questions/65801481/how-to-add-suffix-to-a-plain-text-in-python), or speculating, perhaps you're really looking for URL encoding https://docs.python.org/3/library/urllib.parse.html#urllib.parse.urlencode (which will handle special characters too) – ti7 Jan 22 '21 at 17:25
