如何检查列表中的元素是否存在于其他lis中

Question

如何检查列表中的一个元素是否存在于另一个列表中？如果它真的附加到另一个列表。怎么做我能把所有的值都列出来吗？你知道吗

common=[]

def findCommon(interActor,interActor1):
    for a in interActor:
        if a in interActor1:
            common.append(a)
    return common
interActor=['Rishi Kapoor','kalkidan','Aishwarya']
interActor1=['Aishwarya','Suman Ranganathan','Rishi Kapoor']

Answer 1

interActor=['Rishi Kapoor','kalkidan','Aishwarya']
interActor1=['Aishwarya','Suman Ranganathan','Rishi Kapoor']
anotherlist = []

for x in interActor:
    if x in interActor1:
        anotherlist.append(x)

Answer 2

您可以使用列表理解：

common = [x for x in iter_actor1 if x in iter_actor2]

或使用集合：

common = set(iter_actor1).intersection(iter_actor2)
