Question

我试图用python编写脚本。我需要避免重复相同的任务，并希望写入一个。

catlist1 = ['s0.05-k5-a1.0' , 's0.05-k5-a3.0' , 's0.05-k5-a7.0' , 's0.05-k5-a10.0' ]
catlist2 = ['s0.05-k7-a1.0' , 's0.05-k7-a3.0' , 's0.05-k7-a7.0' , 's0.05-k7-a10.0']

catlist3 = ['s0.07-k5-a1.0' , 's0.07-k5-a3.0' , 's0.07-k5-a7.0' , 's0.07-k5-a10.0' ]
catlist4 = ['s0.07-k7-a1.0' , 's0.07-k7-a3.0' , 's0.07-k7-a7.0' , 's0.07-k7-a10.0']

catlist = [catlist1 ,catlist2 ,catlist3 ,catlist4 ]

我需要调用for循环中的每个列表。我在这个单循环中调用所有列表。我可以通过在catlist1中再次写入多次并再次在catlist2中重复执行此操作。我怎么能解决这个问题。谢谢

for parName in catlist:         

    category = '/home/x/Desktop/rouge/ROUGE/Experiments/' 

    for root, subFolders, files in os.walk(category + parName):
        #i = 0 
        (head, filename) = os.path.split(root)
        print filename
        #some function that is will re

Answer 1

for parName in itertools.chain.from_iterable(catlist):

Answer 2

调用您要执行的操作，展平嵌套列表。你可以这样做

for parName in (item for items in catlist for item in items):

在for循环python中调用多个列表
