python - Capitalized Word Function -

i writing function should take string input , return string every first letter of every word capital letter, have achieved degree.

my code:

string = input("please enter string:")  def capitalize_words(string):     split = string.split()      letter1 = ''     letter2 = ''     letter3 = ''      str1 = split[0]     str2 = split[1]     str3 = split[2]      in str1:         if in str1[0]:             first = i.upper()         else:             letter1 = letter1 +             string1 = (first+letter1)      in str2:         if in str2[0]:             first = i.upper()         else:             letter2 = letter2 +             string2 = (first+letter2)      in str3:         if in str3[0]:             first = i.upper()         else:             letter3 = letter3 +             string3 = (first+letter3)      result = string1+' '+string2+' '+string3     return result   func = capitalize_words(string) print(func) 

input:

please enter string:herp derp sherp 

output:

herp derp sherp 

however inflexible because can enter 3 words spaces no more no less , makes rather primal program. able enter , desired result of first letter of every word being capital letter no matter how many words enter.

i fear skills far able get, can please improve program if possible.

use str.title() achieve want in 1 go.

but process words in sentence, use loop instead of series of local variables; here version same doing arbitrary number of words:

for i, word in enumerate(split):     split[i] = word[0].upper() + word[1:]  result = ' '.join(split) 

i used string slicing select first character, , first character of word. note use of enumerate() give counter wich can replace words in split list directly.
