so I built a side project to help my self with list and while/break. Well I ran into a problem can someone debuf this?

new_list = list()

print('list your siblings once finished type "done" to exit prompt')

while True:
      new = input("sibling name: ')

      if new == "done":
      break

new_list.append(new)

print('tell {} computer says Hi'.format(new_list))

Your

while True: new = input("sibling name: ')

input statement opens with a double quote and ends with a single quote. They must match so the parser knows the difference between items that are apostrophe's and beginning and ends of quoted strings.

Remember that each block of code has a colon to start it and then each statement below it should be indented if it is part of that block.

To the interpreter, you have 2 different blocks of code and not one. The 'if' statement starts at the far left and so does the 'break'. If you indent the 'break' it will be interpreted as part of the 'if' block.

I believe - new_list.append(new) should be before the if statement. This should print the names of all the siblings with the last print statement.

I'm very new to python by I think the "continue" keyword was also missing at the end of the if statement, when running Justin's code above ( with the adjustments from Ron ), when printing the list it was only printing the string "done", as if that was the only item in the list, below is a slightly modified version that seems to work. 

sibling_list = list()

print('Please list your siblings once finished type "DONE" to exit the prompt')

while True:
    sibling = input("sibling name: ")

    if sibling == "DONE":
        break

    sibling_list.append(sibling)
    print("Sibling added! So far you have {} siblings.".format(len(sibling_list)))
    continue

print ("Here are all the Sibling on your list:")    

print('Be sure to tell ' + ', '.join(sibling_list) + ' that the computer says Hi.')
