python退出功能 [英] python return out of function
问题描述
SyntaxError:'return'外部函数
这似乎很好理解,但只要 I 可以看到return是里面一个函数。
这里是我的代码:
def getLinks(self,url,fandom,soup):
links = []
searchElementDict = {
'aff':'select','fcwd': 'select','ffn':'select','tthm':'select','lua':'select','ffa':'select',
'hpfd':'select','phns ':'select','mbba':'div','avgf':'div','mugn':'select','hpffa':'select',
'hpff':'select',
}
如果在searchElementDict中有粉丝:
searchElement = searchElementDict [fandom]
searchElementForDict = {
'aff':'name','fcwd' :'name','ffn':'标题','tthm' :'name','lua':'class','ffa':'class',
'hpfd':'name','phns':'name','mbba':'id',' avgf':'id','mugn':'name','hpffa':'name',
'hppf':'name',
}
如果在searchElementForDict中有粉丝:
searchElementFor = searchElementForDict [fandom]
withValueDict = {
'aff':'chapnav','fcwd':'goto','ffn':'章节导航',' tthm':'chapnav','lua':'textbox',
'ffa':'locationSelect','hpfd':'sid','phns':'chao','mbba':'mibba- 'chapter','hpff':'chapterid',
}
如果粉丝在withValueDict:
withValue = withValueDict [fandom]
try:
if fandom =='mbba'or fandom =='avgf':
chapterGroup = soup.find( searchElemen t,attrs = {searchElementFor:withValue})
individualChapters = chapterGroup.findAll('a')
对于每个单独的章节:
chapterLink = each ['href']
链接.append(chapterLink)
else:
chapterGroup = soup.find(searchElement,attrs = {searchElementFor:withValue})
individualChapters = chapterGroup.findAll('option',attrs = {'value =':''})
在单个章节中:
chapterLink = each.get('value')
links.append(chapterLink)
if fandom =='fcwd ':
del链接[0]
elif fandom =='hpfd'或者fandom =='hpff':
del链接[0]
del链接[0]
除外:
links.append(1)
返回链接
我显然是错的唱歌的东西,我只是无法弄清楚 。 我怀疑你正在混合标签和空格..你的 def
在它前面有4个空格,随后你使用多个标签进行缩进。
还要注意PEP 8中的以下内容:
Python 3不允许混合使用制表符和空格进行缩进。 / p>
Python 2代码缩进,并带有制表符和空格的混合,应该将
转换为仅使用空格。
当使用-t
选项调用Python 2命令行解释器时,它会发出有关非法混合选项卡和
空格的代码的警告。使用-tt时,这些警告会变成错误。这些选项是强烈建议的

I'm getting a syntax error in Python, the error:
SyntaxError: 'return' outside function
That seems pretty self-explanatory but as far as I can see return is inside a function.
Here is my code:
def getLinks(self, url, fandom, soup):
links = []
searchElementDict = {
'aff':'select', 'fcwd':'select', 'ffn':'select', 'tthm':'select', 'lua':'select', 'ffa':'select',
'hpfd':'select', 'phns':'select', 'mbba':'div', 'avgf':'div', 'mugn':'select', 'hpffa':'select',
'hpff':'select',
}
if fandom in searchElementDict:
searchElement = searchElementDict[fandom]
searchElementForDict = {
'aff':'name', 'fcwd':'name', 'ffn':'title', 'tthm':'name', 'lua':'class', 'ffa':'class',
'hpfd':'name', 'phns':'name', 'mbba':'id', 'avgf':'id', 'mugn':'name', 'hpffa':'name',
'hppf':'name',
}
if fandom in searchElementForDict:
searchElementFor = searchElementForDict[fandom]
withValueDict = {
'aff':'chapnav', 'fcwd':'goto', 'ffn':'Chapter Navigation', 'tthm':'chapnav', 'lua':'textbox',
'ffa':'locationSelect', 'hpfd':'sid', 'phns':'chao', 'mbba':'mibba-layout-parts', 'avgf':'chapters',
'mugn':'chapter', 'hpffa':'chapter', 'hpff':'chapterid',
}
if fandom in withValueDict:
withValue = withValueDict[fandom]
try:
if fandom == 'mbba' or fandom == 'avgf':
chapterGroup = soup.find(searchElement, attrs={searchElementFor : withValue})
individualChapters = chapterGroup.findAll('a')
for each in individualChapters:
chapterLink = each['href']
links.append(chapterLink)
else:
chapterGroup = soup.find(searchElement, attrs={searchElementFor : withValue})
individualChapters = chapterGroup.findAll('option', attrs={'value=':''})
for each in individualChapters:
chapterLink = each.get('value')
links.append(chapterLink)
if fandom == 'fcwd':
del links[0]
elif fandom == 'hpfd' or fandom == 'hpff':
del links[0]
del links[0]
except:
links.append(1)
return links
I'm obviously missing something, I just can't figure out what.
I suspect you are mixing tabs and spaces .. your def
has 4 spaces preceding it, subsequently you are using multiple tabs for indentation.
PEP 8 recommends use of (4) spaces over tabs.
Also note the following from PEP 8:
Python 3 disallows mixing the use of tabs and spaces for indentation.
Python 2 code indented with a mixture of tabs and spaces should be converted to using spaces exclusively.
When invoking the Python 2 command line interpreter with the -t option, it issues warnings about code that illegally mixes tabs and spaces. When using -tt these warnings become errors. These options are highly recommended!
