Trying to split a word separated by a "," in python

Question

ans = input("Enter a sentence: ")

count = ans.count(" ") + 1

final = ""

for i in range(count):

    space = ans.find(" ")
    word = ans[0:space]

    final += word + ","

    ans = ans.replace(word,"")

print(final)

The code above shows my attempt to separate words in a sentence with a ",". After the first loop the variable "word" is empty and does not take on the next part of the sentence. Please help

There are several routes for this, perhaps the simplest and most robust is to .split() and join the strings

this will create a list separated by any whitespace chars and then rebuild a new string with them joined by commas

>>> mystring = "some string with spaces"
>>> ",".join(mystring.split())
'some,string,with,spaces'

You might consider a regex if you need something more robust (like handling a terminating .), and may consider doing both (split, regex, join) for a full solution
