Python list while loop check

my aim is to run the while loop until the user inputs a option that is in my list. If they do the while loop should end.

exchangeCurrency = input("what currency would you like to convert to: ").upper()

myList = ["USD", "ERU", "BRL", "JPY", "TRY"]

while exchangeCurrency != myList:
    print("this is not a valid inpit")
    continue
else:
    break

>Solution :

while True:
    exchangeCurrency = input("what currency would you like to convert to: ").upper()
    if exchangeCurrency in myList:
        break
