我正在尝试使用驼峰命名的四个短语
I'm trying to camelCase four phrases
这里是 Python
的超级初学者。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
我的主要错误消息是 invalid character in identifier in line 2
编辑后我的代码运行正常,但输出:
PPE
ICBINB
H5S
第二行的错误是由于无效字符'.您应该使用单引号 ' ' 或双引号 " " 以空格分隔文本。
然后您可以简单地对每个单词的每个首字母执行 .upper() 以使其变为大写,并在最后将所有单词合并到所需的字符串中。
简单易懂,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()
您仅将 word_upper
变量中的第一个字符转换为大写。要获得所需的输出,您需要做两件事。
- 跳过句子的第一个单词
- 将后续单词的第一个字符替换为大写并将其附加到输出。
为此,您必须更改循环并使用
enumerate()
从循环 (see here) 获取单词索引,然后对于后面的单词仅替换第一个字符。
代码将是
def make_camel_case(word_string):
word_list = word_string.split(' ')
output = ''
for i,word in enumerate(word_list):
if(i != 0):
word_upper = word[0].upper()
word = word_upper + word[1:]
output = output + word
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()
为了更干净的解决方案,使用str.capitalize()
函数(see here) suggested by @federico-baù.然后函数会变成这样,
def make_camel_case(word_string):
word_list = word_string.split(' ')
output = ''
for i,word in enumerate(word_list):
if(i != 0):
word = word.capitalize()
output = output + word
return(output)
