大写的单词…

str = "this is string example....  wow!!!";
print "str.title() : ", str.title();

@Gary02127评论，下面的解决方案适用于带有撇号的标题

import re

def titlecase(s):
    return re.sub(r"[A-Za-z]+('[A-Za-z]+)?", lambda mo: mo.group(0)[0].upper() + mo.group(0)[1:].lower(), s)

text = "He's an engineer, isn't he? SnippetBucket.com "
print(titlecase(text))

另一个解决方案是:

" ".join(map(lambda d: d.capitalize(), word.split(' ')))

你可以试试这个。简单而利落。

def cap_each(string):
    list_of_words = string.split(" ")

    for word in list_of_words:
        list_of_words[list_of_words.index(word)] = word.capitalize()

    return " ".join(list_of_words)

当解决方案简单而安全的时候，为什么你要用连接和for循环来使你的生活复杂化?

只要这样做:

string = "the brown fox"
string[0].upper()+string[1:]

对你的问题最简单的解决方法，在我的情况下是有效的:

import string
def solve(s):
    return string.capwords(s,' ') 
    
s=input()
res=solve(s)
print(res)

如果str.title()对您不起作用，请自己大写。

将字符串拆分为单词列表 每个单词的第一个字母大写 把单词连接成一个字符串

一行程序:

>>> ' '.join([s[0].upper() + s[1:] for s in "they're bill's friends from the UK".split(' ')])
"They're Bill's Friends From The UK"

明显的例子:

input = "they're bill's friends from the UK"
words = input.split(' ')
capitalized_words = []
for word in words:
    title_case_word = word[0].upper() + word[1:]
    capitalized_words.append(title_case_word)
output = ' '.join(capitalized_words)
