Using while loop in a function and then the same function in the while loop [Python]

I wrote this code to create a function that removes items from list

ToDo = ["Python", "Java", "Electronics"]
def remove(list):
print("Currently you have following items in: ")
display(list)
answer= input ("Do you want to continue yes/no ") 
while answer.lower() == "yes":
    list.remove(input("Enter the Value you want to remove"))
    print("List Updated")
    remove(list)

  def display(list):
  for item in list:
    print(item)

While calling remove() fucntion in python interactive mode

treehouse:~/workspace$ python -i work.py

remove(ToDo)
Currently you have following items in:
Python
Java
Electronics
Do you want to continue yes/no yes Enter the Value you want to remove Electronics
List Updated
Currently you have following items in:
Python
Java
Do you want to continue yes/no no
Enter the Value you want to remove _

Why it's asking again to remove the value even if I wrote no in last second line. What's wrong with my code?

Hi, -- program starts -- answer gets 'yes' # you set answer yes -- while loop runs -- remove the item -- (second) program starts again # but this time the program is running inside while loop -- inside program prompts for answer -- if you set answer 'no' -- (second) while loop inside the second(program) does not run -- jumps back to the beginning of the first while loop In other words, it will run infinitely until you run out of list items
