[Tutor] about \

[Hugo González Monteverde]

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.
