求助，带有特殊字符如何拆分？

[jarodzhao]

ss = "'name':'Love up,love cup. 卡通大肚 陶瓷马克杯','id':'8746089' , 'price':'16','brand':'Love up,love cup.' ,'mall':'天猫精选', 'category':'日用百货/厨房用具/水具酒具/陶瓷杯','metric1':'16','dimension10':'tmall.com','dimension9':'faxian','dimension11':'1阶价格','dimension12':'天猫精选','dimension20':'无','dimension32':'先发后审','dimension25':'10162'"
print(ss)
print()

sss = ss.split(',')
for s in sss:
print(s)

本来用逗号分挺好的，突然有条数据里name值里有逗号，造成分割出现问题。数据的格式是固定的，求助如何分割不出问题？

回2楼，我尝试过用这种方法分割。但是有些数据中,和'之间会有空格，所以这个方案被pass了

\s* 表示若干个空格(可以是0个)

import re

ss = "'name':'Love up,love cup. 卡通大肚 陶瓷马克杯','id':'8746089'  , 'price':'16','brand':'Love up,love cup.' ,'mall':'天猫精选', 'category':'日用百货/厨房用具/水具酒具/陶瓷杯','metric1':'16','dimension10':'tmall.com','dimension9':'faxian','dimension11':'1阶价格','dimension12':'天猫精选','dimension20':'无','dimension32':'先发后审','dimension25':'10162'"

sss = re.split(r"'\s*,\s*'",ss)
for item in sss:
	s=item.replace("'","")
	print(s)

这样子简单点，也有复杂点的办法

用我这个方法对于有单引号转义也没有问题

>>> raw_str = "{'name':'Jack N\'Jil l, 杰克吉尔 牙刷兔子图案1支+儿童牙膏香蕉味 50g','id':'8753131' , 'price':'11','brand':'' ,'mall':'Amcal中文官网', 'category':'母婴用品/洗护用品/婴儿护理用品/婴儿口腔护理','metric1':'11','dimension10':'amcal.com.au','dimension9':'faxian','dimension11':'1阶价格','dimension12':'Amcal中文官网','dimension20':'无','dimension32':'无','dimension25':'769'}"
>>> d = eval(repr(raw_str))

引用 5 楼 u012536120 的回复:

import re

ss = "'name':'Love up,love cup. 卡通大肚 陶瓷马克杯','id':'8746089'  , 'price':'16','brand':'Love up,love cup.' ,'mall':'天猫精选', 'category':'日用百货/厨房用具/水具酒具/陶瓷杯','metric1':'16','dimension10':'tmall.com','dimension9':'faxian','dimension11':'1阶价格','dimension12':'天猫精选','dimension20':'无','dimension32':'先发后审','dimension25':'10162'"
sss = re.findall(r"('.*?':'.*?')",ss,re.S)

for item in sss:
	print(item)

含有逗号的情况解决了，谢谢 但是又遇到一种情况，含有单引号，还有转义符。。。麻烦再帮忙看看

import re

a = ("gtmAddToCart({'name':'Jack N\'Jil l, 杰克吉尔 牙刷兔子图案1支+儿童牙膏香蕉味 50g','id':'8753131' , 'price':'11','brand':'' ,'mall':'Amcal中文官网', 'category':'母婴用品/洗护用品/婴儿护理用品/婴儿口腔护理','metric1':'11','dimension10':'amcal.com.au','dimension9':'faxian','dimension11':'1阶价格','dimension12':'Amcal中文官网','dimension20':'无','dimension32':'无','dimension25':'769'})")

b = re.findall(r"(\'.*?'\:\'.*?\')", a, re.S)


print(type(b))

另，想看看正则表达式，有没有什么书籍推荐一下？

麻烦看一下7楼的情况，能不能直接拆解成字典？谢谢先

正则推荐：https://www.cnblogs.com/deerchao/archive/2006/08/24/zhengzhe30fengzhongjiaocheng.html 这个多看几遍，就能稍微有点感觉了 你这个得具体问题具体分析了

问题越来越复杂，不但有单引号，还有逗号，还有/。。。准备买本书好好学一下正则表达式
