How do I change the value of a variable to lowercase in Python?

For example, when "I study Python programming at KAIST Center for Gift Education." is the value of this variable, how do i make it "i study python programming at kaist center for gifted education"?

I would try using .replace() and .lower()

stringEx = stringEx.lower()

output

i study python programming at kaist center for gift education.

Just use the lower function

string.lower()

And here is the official documents.

  • how do i use that in code? my code is sentence = 'I study Python programming at KAIST Center For Gifted Education.' # Initialise counters: vowels = { 'a': 0, 'e': 0, 'i': 0, 'o': 0, 'u': 0, } # for char in sentence: if char in vowels: vowels[char] += 1 print(vowels['a']) print(vowels['e']) print(vowels['i']) print(vowels['o']) print(vowels['u']) – Aiden 1L8L May 23 '21 at 05:34
  • @Aiden that's another question, but if you need to count occurrence of some characters in the string you can use `count` function. first convert sentence to lower case and then: for char in vowels: vowels[char] = sentence.count(char) – aaronn May 23 '21 at 05:44
