finding which element is wrong in list(python)

Question

I have two lists, englishclub and listofallclub

I have already checked that not all elements in englishclub are in listofallclub, but I want to find which element is missing from listofallclub

I expect the lists to be very large.

listallclub = df.Club.tolist()

result =  all(elem in englishclub  for elem in  listallclub)

if result:
    print("Yes, englishclub  contains all elements in listallclub")    
else :
    print("No, englishclub  does not contains all elements in listallclub")

I would like my outputto be the list of elements that are in englishclub but not in listofallclub

You can use list comprehension,

e = [ec for ec in englishclub if ec not in listallclub]

if e:
    print("No, englishclub  does not contains all elements in listallclub")
    print("And they are")
    print(e)
else :
    print("Yes, englishclub  contains all elements in listallclub")
