题目：给定一段英文文本（单词间都是空格分隔），请编写一个函数，将每个单词的首字母转成大写。

def to_capital(words):
    # your codes

示例：

输出："Hogwarts School Of Witchcraft And Wizardry"

手机上手码的，缩进可能不标准

def to_capital(worlds):
print (worlds.title())

3 
def to_capital(words):
    return ' '.join([x.capitalize() for x in words.split()])

assert to_capital('hogwarts school of witchcraft and wizardry') == 'Hogwarts School Of Witchcraft And Wizardry'

print(strl.title())

6 
def  fn(ss):
    res=''
    sss=ss.split(' ')
    for i in range(len(sss)):
        a=sss[i].capitalize()  #首字母大写然后赋值给a
        if i<len(sss)-1:
            res=res+a+' '
        else:
            res = res + a
    return res
7 
a ="hogwarts school of witchcraft and wizardry"
print(a.title())

还有这么简单的方法

9 
return words.title()
10 
def to_capital(words):
    return ' '.join(w.capitalize() for w in words.split(' '))
12

def fun():
s = input(“请输入一串英文：”)
sa=s.title()
return sa
print(fun())

13 
def to_capital(words):
    return ''.join([word.upper() if (idx == 0 or words[idx - 1] == ' ') else word for idx, word in enumerate(words)])


assert to_capital("hogwarts school of witchcraft and wizardry") == "Hogwarts School Of Witchcraft And Wizardry"
14 
    public static String toCapital(String words) {
        List<String> res_list = new ArrayList<String>();
        String[] words_list = words.split(" ");
        for (String word : words_list) {
            word = word.substring(0, 1).toUpperCase() + word.substring(1);
            res_list.add(word);
        }
        return String.join(" ", res_list);
    }
