SyntaxError when i used interpreter

[gontajones]

You need to add one more ENTER after f.write(data).

>>> f = open ("C:/doit/newfile.txt", 'w')
>>> for i in range(1,11):
...     data = "%d line. \n" % i
...     f.write(data)
<<ENTER AGAIN HERE>>
>>> f.close()

Doing this the interpreter will "close" the for loop.
