問題描述

初學(xué)python，最近嘗試爬數(shù)據(jù)，json字符串的value中有冒號(hào)，需要去掉。我的代碼如下。 a和b都是value中會(huì)有冒號(hào)的字符串

import rea = 'Title:’Intern: Customer Experience + Innovation (CX+I) Intern Brands’'b = 'cmp:’Adecco: USA’,cmpesc:’Adecco: USA’'result = re.sub(’^(?:Title|cmp|cmpesc):.+(:)’,’’, a)

代碼執(zhí)行結(jié)果是只剩 Customer Experience + Innovation (CX+I) Intern Brands’，之前的內(nèi)容全被刪除了，而我想要的效果是只刪intern之后的那個(gè)冒號(hào)（title后的冒號(hào)要保留）。請(qǐng)問大家該如何修改？

問題解答

import reresult = re.sub(’^(Title|cmp|cmpesc:)(.+):(.*)’,’123’,'Title:’Intern: Customer Experience + Innovation (CX+I) Intern Brands’')print(result) # Title:’Intern Customer Experience + Innovation (CX+I) Intern Brands’回答2：

這樣的話：

’’.join(re.split(’(?<![Title|cmp|cmpesc]):’,a))

就好了

果然是我看錯(cuò)題目了....

不用去掉冒號(hào)，直接變成字典就行了~

>>> a = 'Title:’Intern: Customer Experience + Innovation (CX+I) Intern Brands’';b = 'cmp:’Adecco: USA’,cmpesc:’Adecco: USA’'>>> dict([s.split(’:’,1) for s in a.split(’,’)]){’Title’: '’Intern: Customer Experience + Innovation (CX+I) Intern Brands’'}>>> dict([s.split(’:’,1) for s in b.split(’,’)]){’cmpesc’: '’Adecco: USA’', ’cmp’: '’Adecco: USA’'}>>>

寫成函數(shù)

a = 'Title:’Intern: Customer Experience + Innovation (CX+I) Intern Brands’'b = 'cmp:’Adecco: USA’,cmpesc:’Adecco: USA’'def fn(x): return dict((s.split(’:’,1) for s in x.replace('’','').split(’,’)))print(fn(a))print(fn(b))# {’Title’: ’Intern: Customer Experience + Innovation (CX+I) Intern Brands’}# {’cmp’: ’Adecco: USA’, ’cmpesc’: ’Adecco: USA’}
