我正在尝试使用驼峰命名法四个短语

Question

超级初学者到Python这里。到目前为止，这是我的代码：

def make_camel_case(word_string):
    word_list = word_string.split(’ ’)
    output = ’’
    for word in word_list:
        word_upper = word[0].upper()
        output = output+word_upper
    return(output)
def camel_case():
    phrase1 = ’purple people eater’
    phrase2 = ’i can\’t believe it\’s not butter’
    phrase3 = ’heinz 57 sauce’
    print(make_camel_case(phrase1))
    print(make_camel_case(phrase2))
    print(make_camel_case(phrase3))
camel_case()

这是我想要的输出：

purplePeopleEater
iCan’tBelieveIt’sNotButter
heinz57Sauce

我的主要错误信息是 invalid character in identifier in line 2

编辑后我的代码运行正常，但输出：

 PPE
 ICBINB
 H5S

Answer 1

简单点，只需使用capitalize()函数：

def make_camel_case(word_string):
    word_list = word_string.split(' ')
    output = ''

    for word in word_list:
        word_upper = word.capitalize()
        output += word_upper
    return output
def camel_case():
    phrase1 = 'purple people eater'
    phrase2 = "i can't believe it’s not butter"
    phrase3 = 'heinz 57 sauce'
    print(make_camel_case(phrase1))
    print(make_camel_case(phrase2))
    print(make_camel_case(phrase3))
camel_case()

Answer 2

第二行引起的错误是由无效字符 '. 您应该使用单引号 ' ' 或双引号 " " 按空格分隔文本。

然后你可以简单地对每个单词的每个第一个字母执行 .upper() 使其大写，最后，将所有单词合并到所需的字符串中。
