获取两个列表的匹配

Question

我有两个列表，我喜欢浏览它们以获得匹配和差异 但我不明白为什么我的索引没有达到列表的末尾 有我的代码：

recordedEvents=[u'/app//wakeup', u'/app/hdmi/state', u'/homepage/ws/view', u'/homepage//activate', u'/live//activate', u'/live//zap', u'/live/ctazap/view', u'/live/ppluspminus/zap', u'/app//keypress', u'/app//keypress', u'/app//keypress', u'/app//keypress', u'/app//keypress', u'/app//keypress', u'/live/virtualzappinglistbanner/zap', u'/live/virtualzappinglistbanner/view', u'/live/digit/zap', u'/live/noright/view', u'/live/digit/zap', u'/live/ctazap/view', u'/live/ctazap/click', u'/live/toolbox/view', u'/app//keypress', u'/live/toolbox/click', u'/isf//activate', u'/app//keypress', u'/live//activate', u'/live//zap', u'/live/ctazap/view', u'/live/ctazap/click', u'/live/toolbox/view', u'/app//keypress', u'/app//keypress', u'/app//keypress', u'/app//standby', u'/app/favorites/state', u'/app/optin/state', u'/app/perso/state', u'/app/tnt/state', u'/app/hdd/state', u'/app/switches/state', u'/qos/live/', u'/trap//temperature'] 
expectedEvents=[u'/app//wakeup', u'/app/hdmi/state', u'/homepag/ws/view', u'/homepage//activate', u'/live//activate', u'/live//zap', u'/live/ppluspminus/zap', u'/app//keypress', u'/live/virtualzappinglistbanner/zap', u'/live/virtualzappinglistbanner/view', u'/live/digit/zap', u'/live/noright/view', u'/live/digit/zap', u'/live/toolbox/view', u'/live/toolbox/click', u'/isf//activate', u'/app//keypress', u'/live//activate', u'/live//zap', u'/live/toolbox/view', u'/live/toolbox/click', u'/app//standby', u'/app/favorites/state', u'/app/optin/state', u'/app/perso/state', u'/app/tnt/state', u'/app/hdd/state', u'/app/switches/state', u'/qos/live/', u'/trap//temperature'] 


indexR = 0 
indexE = 0 
n_expected_event=['ctazap'] 
while indexR!=len(recordedEvents)-1: 
if recordedEvents[indexR]==expectedEvents[indexE]: 
    print "[event]"+str(expectedEvents[indexE])+" Matching OK" 
    indexE+=1 
    indexR+=1 
else: 
    for diff in n_expected_event: 
     if str(diff) in str(recordedEvents[indexR]): 
      print"[missing] "+str(recordedEvents[indexR]) 
    indexR+=1 

有结果：

[event]/app//wakeup Matching OK 
[event]/app/hdmi/state Matching OK 
[event]/homepage/ws/view Matching OK 
[event]/homepage//activate Matching OK 
[event]/live//activate Matching OK 
[event]/live//zap Matching OK

您可以使用set操作来做到这一点。你要求的基本上是set.intersection和set.difference。

>>> set(recordedEvents).intersection(expectedEvents) 
{'/app/optin/state', 
'/live/virtualzappinglistbanner/zap', 
'/qos/live/', 
'/live/ppluspminus/zap', 
'/live/noright/view', 
'/live/digit/zap', 
'/live//zap', 
'/homepage//activate', 
'/trap//temperature', 
'/app/tnt/state', 
'/app//standby', 
'/app/switches/state', 
'/live/toolbox/view', 
'/app/perso/state', 
'/live/virtualzappinglistbanner/view', 
'/app//wakeup', 
'/app/hdd/state', 
'/app/favorites/state', 
'/app/hdmi/state', 
'/isf//activate', 
'/app//keypress', 
'/live//activate', 
'/live/toolbox/click'} 

>>> set(recordedEvents).difference(expectedEvents) 
{'/live/ctazap/view', 
'/live/ctazap/click', 
'/homepage/ws/view'} 

然后你不需要自己做任何迭代。如果您仍想用格式打印，则可以这样做。

>>> for i in set(recordedEvents).intersection(expectedEvents): 
    print('[event]{} Matching OK'.format(i)) 

[event]/app/optin/state Matching OK 
[event]/live/virtualzappinglistbanner/zap Matching OK 
[event]/qos/live/ Matching OK 
[event]/live/ppluspminus/zap Matching OK 
[event]/live/noright/view Matching OK 
[event]/live/digit/zap Matching OK 
[event]/live//zap Matching OK 
[event]/homepage//activate Matching OK 
[event]/trap//temperature Matching OK 
[event]/app/tnt/state Matching OK 
[event]/app//standby Matching OK 
[event]/app/switches/state Matching OK 
[event]/live/toolbox/view Matching OK 
[event]/app/perso/state Matching OK 
[event]/live/virtualzappinglistbanner/view Matching OK 
[event]/app//wakeup Matching OK 
[event]/app/hdd/state Matching OK 
[event]/app/favorites/state Matching OK 
[event]/app/hdmi/state Matching OK 
[event]/isf//activate Matching OK 
[event]/app//keypress Matching OK 
[event]/live//activate Matching OK 
[event]/live/toolbox/click Matching OK 

>>> for i in set(recordedEvents).difference(expectedEvents): 
    print('[missing] {}'.format(i)) 

[missing] /live/ctazap/view 
[missing] /live/ctazap/click 
[missing] /homepage/ws/view
