This is the code i have so far but i want it to treat the lower case and upper case words the same not sure how to though any ideas?(E.g. CASE, case and CAse the same).

sentence= input("Enter a sentence")
keyword= input("Input a keyword from the sentence")
words = sentence.split(' ')

for i, word in enumerate(words):`enter code here`
    if keyword == word:
        print(i+1)

To compare two words ignoring case, simply convert them both to, e.g., lower case: word1.lower() == word2.lower().

You can use str.upper() or str.lower() to turn a string into either all uppercase or all lowercase respectively.

  • On Python >= 3.3, [str.casefold()](https://docs.python.org/3/library/stdtypes.html#str.casefold) is most appropriate, which is specifically designed to remove case information. – SethMMorton Feb 02 '17 at 20:59

to treat the lower case and upper case words the same

Use str.lower() function:

for i, word in enumerate(words):
    if keyword.lower() == word.lower():
        print(i+1)
