让我们说drug_input = 'METHADONE'

我需要能够浏览b array并删除没有任何一行的每一行：

['ALGIDON','ALGOLYSIN','AMIDON','DEPRIDOL','DOLOPHINE','FENADONE',
                      'METHADOSE','MIADONE','PHENADONE']

例如，如果b[1] = "yes,no,yes,amidon,blah"则不执行任何操作

但

if b[2] = "yes,yes,yes,vicodin,yes"然后删除此记录

Answer 1

我没有真正阅读你的代码段落，但是从你之后描述的问题中听起来像你想要的那样：

needed = set(['ALGIDON','ALGOLYSIN','AMIDON','DEPRIDOL','DOLOPHINE','FENADONE', 'METHADOSE','MIADONE','PHENADONE'])
b = filter(lambda s: len(set(s.upper().split(',')) & needed) > 0, b)

python：复杂的循环列表
