蟒蛇：通过数组

迭代我有一个这样的名单：蟒蛇：通过数组

brand_names={'MORPHINE':['ASTRAMORPH','AVINZA','CONTIN','DURAMORPH','INFUMORPH',

         'POLYGESIC','STAGESIC','SYMTAN','SYNKONIN','TUSSIONEX','VICODIN', 
         'VICOPROFEN','XODOL','ZYDONE']}

我想知道是否在brand_names['OXYCODONE':]或brand_names['HYDROCODONE:] == SOME_VALUE什么

这样的事情？

for brand in brand_names['OXYCODONE','HYDROCODONE']: 
    if brand = some_value: 
    append to arrayC

这不是一个列表 - 它是一个字典。 – 2010-07-28 19:19:24

19在最后一天的Python CSV问题，可能读了一些文档？ – katrielalex 2010-07-28 19:33:01

这甚至不是一个CSV问题。 – 2010-07-28 19:33:41

if any(some_value in brand_names[key] for key in ('OXYCODONE','HYDROCODONE')): 
    append to arrayC

for brand in ['OXYCODONE','HYDROCODONE']: 
    if some_value in brand_names[brand]: 
     print brand

而不是写一个for循环，并追加到一个列表，你可以代替它写成一个列表理解：

somevalue = 'EUKODAL' 
result = [brand_name for brand_name in ['OXYCODONE', 'HYDROCODONE'] 
      if somevalue in brand_names[brand_name]] 
print result

结果：

 
['OXYCODONE']

不需要循环，你可以这样做：

'some_value' in brand_names['OXYCODONE'] + brand_names['HYDROCODONE']

这里有一个答案，如果你需要做很多事情。然后，建立一次可用于立即访问反向查找的查阅字典是值得的。
