How to change a tuple into array in Python?

Question

Let's say I have a tuple t = (1,2,3,4). What's the simple way to change it into Array?

I can do something like this,

array = []
for i in t:
    array.append(i)

But I prefer something like x.toArray() or something.

If you're passing your "array" (list) to a function that wants an iterable, virtually all of them will happily take a list, tuple, numpy.array, yourawesomeiterabletype, whatever. — Nick T

First, Python doesn't have "array"s. It has sequences, including list and tuple. Why do you want to change one sequence into another? — S.Lott

If you want to convert a tuple to a list (as you seem to want) use this:

>>> t = (1, 2, 3, 4)   # t is the tuple (1, 2, 3, 4)
>>> l = list(t)        # l is the list [1, 2, 3, 4]

In addition I would advise against using tupleas the name of a variable.

+1. Correct answer and apt advice against using names of built in functions as variable names.

+1 As simple as this answer seems, it is not always obvious to n00bs in the Python world.
