Hi,
The '\' character is used to break lines and ask the interpreter to
treat them as a single line, but Python is smart enough to allow
breaking lines inside parenthesis and braces...so:
NOT WORKING:
>>> a, e, i, o, u = 1, 2,
Traceback (most recent call last):
File "<stdin>", line 1, in ?
ValueError: unpack tuple of wrong size
>>> 3, 4, 5
File "<stdin>", line 1
3, 4, 5
^
SyntaxError: invalid syntax
WORKS:
>>> (a, e, i, o, u) = (1, 2,
... 3, 4, 5)
>>>
What's the difference? The parenthesis... the interpreter sees the open
parenthesis and assumes correctly that the line is not yet finished.
