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

，我喜歡將其分割爲：

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

...

我有織物和織物類型的查找表，如：

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

任何意見非常讚賞

條目的變量是多少？我懷疑每行可以有多個結構，只有一個fabric_type？ – 2014-09-02 10:47:52

這裏是列表https://gist.github.com/nkhine/fa51bb6cb6f958efd80f – khinester 2014-09-02 10:55:37

有了一個表達：

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，這些單片的正則表達式是慢...與狀態機大概標記化一個更好的主意......

UPDATE/w您的清單：

但是，您需要使用列表中的材料擴展結構列表...其實我是爲您做的，因爲只有'Certified Organic Cotton'從列表中缺失。

沒有指定分隔符，只有關鍵字，所以找到每個關鍵字百分比，在結構的情況下，或在fabric_type情況下的前導字符串。
試試這個

>>> 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']]
