I am required to capitalize the first letter of each word and then return the modified string

I tried this Python function

def solve(s):
ret = ""
words = s.split(" ")
capitalized = []
for word in words:
first = word[0].upper() # capitalize the first character
ret += first # add it to our string
for i in range(1,len(word)):
ret += str(word)

# get the number of words in the sentence for space insertion
# if the words are three then you need two spaces(N-1)
cnt = len(words)
idx = 0
y = ""
# loop through checking for uppers and insert a space
for i in range(len(ret)):
if ret.isupper() and idx != cnt:
y+= " " # add a space and then increment index
y+=ret
idx+=1
elif ret.islower():
y += ret

return y



It is giving me the right output but somehow its adding extra space(s) at the end of the concatenated word
