Making my While loop terminate with the input of "Done"

I am currently writing a program for my Intro to Programming class. The requirements are to have a user input a list of celebrity names, add them to a list, print out how many celebrities were entered, and then to print the list of the celebrities that were entered. I must use a loop, so I employed a while loop; however I cannot make it end when the user inputs Done to the names input field.

Below is the code, and my attempt at using an if else statement to control the loop.

def main():      celebs = []        again = 'y'        while again == 'y':          name = input('Enter a name: ')          if name == 'Done':              again == 'n'          else:              again == 'y'              celebs.append(name)            print('You entered ',len(celebs), 'celebrities to the list')      print('   ')      print('The ',len(celebs),'celebrities you entered were: ')        for name in celebs:          print(name)  main()

Change the double equals to a single equals in the statements inside the if/else. You need to assign a value to 'again', but the double equals is just comparing instead.

Alternatively, you could look up the use of the 'break' statement.

Use == for comparisons and = for assignments. That should do the trick.

If name == "Done", you should do:

again = 'n' # not again == 'n'  

(Similarly for setting again = 'y', although I think that line is unnecessary, since again is already equal to 'y'.)

You have a comparison operator in your code instead of assignment.

Change again == 'n' to again = 'n' and again == 'y' to again = 'y'

To avoid adding 'Done' to your list, skip to next iteration:

while again == 'y':      name = input('Enter a name: ')      if name == 'Done':          again = 'n'          continue      else:          again = 'y'      celebs.append(name)  

which can be simplified to:

while again == 'y':      name = input('Enter a name: ')      if name == 'Done':          again = 'n'          continue      celebs.append(name)  

it is also better to use bool value here:

again = True  while again:      name = input('Enter a name: ')      if name == 'Done':          again = False          continue      celebs.append(name)  

or you can just use break:

while True:      name = input('Enter a name: ')      if name.strip() == 'Done':          break      celebs.append(name)
