如何檢查列表中的元素是否存在於另一個列表中

Question

如何檢查列表中的元素是否存在於另一個列表中，以及是否確實將其追加到另一個列表中，如何使它獲取列表中的所有值？

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

您可以使用列表推導來實現：

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

或使用集合：

common = set(iter_actor1).intersection(iter_actor2)

Answer 2

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

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