python使用re和查找列表进行拆分

我必须分割一个包含如下符号的字符串：

80% Combed Cotton 20% Polyester Brushed 3-ply 320 g/m2
70% Bamboo Viscose 30% Organic Cotton Fine Jersey 115g / 3.4 oz

我喜欢把它分成：

('80% Combed Cotton', '20% Polyester', 'Brushed 3-ply', '320 g/m2')
('70% Bamboo Viscose', '30% Organic Cotton', 'Fine Jersey', '115g / 3.4 oz')

...

我有一个面料和面料类型的查找列表，例如：

fabric = ['Combed Cotton', 'Polyester', 'Organic Cotton', 'Bamboo Viscose']
fabric_type = ['Brushed 3-ply', 'Fine Jersey']

任何建议非常感谢

没有指定分隔符，只指定了关键字，因此在Fabric格式中找到每个关键字的百分比，或者在fabric_type情况下找到前导字符串。
试试这个

>>> lines = ['80% Combed Cotton 20% Polyester Brushed 3-ply 320 g/m2',
... '70% Bamboo Viscose 30% Organic Cotton Fine Jersey 115g / 3.4 oz']
>>> fabrics = ['Combed Cotton', 'Polyester', 'Organic Cotton', 'Bamboo Viscose']
>>> fabric_types = ['Brushed 3-ply', 'Fine Jersey']
>>> import re
>>> result = []
>>> for line in lines:
...     product = []
...     for fabric in fabrics:
...         for match in re.findall('[\d\s%%]*\s%s'%fabric, line):
...             product.append(match.strip())
...     for fabric_type in fabric_types:
...         for match in re.findall('%s.+'%fabric_type, line):
...             product.append(fabric_type)
...             product.append(match.replace(fabric_type,"").strip())
...     if res:
...         result.append(product)
... 
>>> result
[['80% Combed Cotton', '20% Polyester', 'Brushed 3-ply', '320 g/m2'], ['30% Organic Cotton', '70% Bamboo Viscose', 'Fine Jersey', '115g / 3.4 oz']]

用一个表达式：

import re
fabric = ['Combed Cotton', 'Polyester', 'Organic Cotton', 'Certified Organic Cotton', 'Bamboo Viscose']
fabric_type = ['Brushed 3-ply', 'Fine Jersey']

test_cases = [
    "80% Combed Cotton 20% Polyester Brushed 3-ply 320 g/m2", 
    "70% Bamboo Viscose 30% Organic Cotton Fine Jersey 115g / 3.4 oz"]

fabric_rx = re.sub("\s+","\s+","|".join(fabric))
fabric_type_rx = re.sub("\s+","\s+","|".join(fabric_type))

expr = "(?:\d{1,3}\%\s(?:"+ fabric_rx +")(?:\s+))|(?:"+ fabric_type_rx +"(?:\s+))|(?:.{2,})"
rx = re.compile(expr)

for test in test_cases:
    results = re.findall(rx, test)
    for idx, item in enumerate(results):
        results[idx] = item.strip()
    print results

但是这些整体的正则表达式很慢......用状态机进行标记化可能是一个更好的想法......

fabric_type = ['Brushed 3-ply', 'Fine Jersey']

但是您需要使用列表中的材料扩展结构列表......实际上我是为您做的，因为列表中缺少“有机认证棉花”。
