2129. Capitalize the Title 變正常的句子

 You are given a string title consisting of one or more words separated by a single space, where each word consists of English letters. Capitalize the string by changing the capitalization of each word such that:

• If the length of the word is 1 or 2 letters, change all letters to lowercase.
• Otherwise, change the first letter to uppercase and the remaining letters to lowercase.

Return the capitalized title.

 

Example 1:

Input: title = "capiTalIze tHe titLe"
Output: "Capitalize The Title"
Explanation:
Since all the words have a length of at least 3, the first letter of each word is uppercase, and the remaining letters are lowercase.

Example 2:

Input: title = "First leTTeR of EACH Word"
Output: "First Letter of Each Word"
Explanation:
The word "of" has length 2, so it is all lowercase.
The remaining words have a length of at least 3, so the first letter of each remaining word is uppercase, and the remaining letters are lowercase.

Example 3:

Input: title = "i lOve leetcode"
Output: "i Love Leetcode"
Explanation:
The word "i" has length 1, so it is lowercase.
The remaining words have a length of at least 3, so the first letter of each remaining word is uppercase, and the remaining letters are lowercase.

 

Constraints:

• 1 <= title.length <= 100
• title consists of words separated by a single space without any leading or trailing spaces.
• Each word consists of uppercase and lowercase English letters and is non-empty.

解法照做: 如果長度<=2: 全部變成小寫

如果長度超過3 就用capitialize 變成正常

                ans.append(i.lower())
            else:
                ans.append(i.capitalize())
