More elegant way of declaring multiple variables at the same time

Question

To declare multiple variables at the \"same time\" I would do:

a, b = True, False

But if I had to declare much more variables, it turns les

Answer 1

I like the top voted answer; however, it has problems with list as shown.

  >> a, b = ([0]*5,)*2
  >> print b
  [0, 0, 0, 0, 0]
  >> a[0] = 1
  >> print b
  [1, 0, 0, 0, 0]

This is discussed in great details (here), but the gist is that a and b are the same object with a is b returning True (same for id(a) == id(b)). Therefore if you change an index, you are changing the index of both a and b, since they are linked. To solve this you can do (source)

>> a, b = ([0]*5 for i in range(2))
>> print b
[0, 0, 0, 0, 0]
>> a[0] = 1
>> print b
[0, 0, 0, 0, 0]

This can then be used as a variant of the top answer, which has the "desired" intuitive results

>> a, b, c, d, e, g, h, i = (True for i in range(9))
>> f = (False for i in range(1)) #to be pedantic
