Python indentation mystery

Question

Why am I getting the following error? The last print statement should not be a part of the while loop.

>>> while n>= 0:
...     n = n-1
...     print(n)
... print ("TO A!!")
  File "<stdin>", line 4
    print ("TO A!!")
        ^
SyntaxError: invalid syntax

Answer 1

You need to press enter after your while loop to exit from the loop

>>> n = 3
>>> while n>=0:
...     n = n-1
...     print (n)
...                         # Press enter here

0
-1
>>> print ("To A!!")
To A!!

Note:- ... implies that you are still in the while block
