How convert list in tuple???

[Guest_imported]

An other question:

How can I convert a list in a tuple?
I tried:
>>> a = ["A","B","C"]
>>> b = tuple(a) #I found this hint on >>>#

Traceback (most recent call last):
File &quot;<pyshell#15>&quot;, line 1, in ?
b = tuple(a)
TypeError: object of type 'tuple' is not callable

Your glitch is the &quot;=&quot; operator.

>>> a = [&quot;A&quot;,&quot;B&quot;,&quot;C&quot;]
>>> tuple(a)
('A', 'B', 'C')
>>>

a is now a tuple.

Is this what you wanted?

I don't know why but know it works in this way...

>>> a = [&quot;A&quot;,&quot;B&quot;,&quot;C&quot;]
>>> b = tuple(a)
>>> print b
('A', 'B', 'C')

Why there's an error in the previous example?
