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 less and less elegant:
a, b, c, d, e, f, g, h, i, j = True, True, True, True, True, False, True ,True , True, True
Is there a better / elegant / convenient way to do this?
This must be very basic, but if I do used a list or a tuple for storing the variables, how would I have to approach so that I would be helpful since:
aList = [a,b]
Is not valid, I would have to do:
a, b = True, True
Or what am I missing?

Declaring multiple variables in a single declaration can cause confusion regarding the types of the variables and their initial values. If more than one variable is declared in a declaration, care must be taken that the type and initialized value of the variable are handled correctly.
You can assign the same value to multiple variables by using = consecutively. This is useful, for example, when initializing multiple variables to the same value. It is also possible to assign another value into one after assigning the same value.
Yes you can and it is slightly more nuanced than it seems. You can use the same syntax in function parameter declarations: func foo(a, b string) { // takes two string parameters a and b ... } Then comes the short-hand syntax for declaring and assigning a variable at the same time.
Declaring multiple variables in a single declaration could cause confusion about the types of variables and their initial values. In particular, do not declare any of the following in a single declaration: Variables of different types.
a, b, c, d, e, g, h, i, j = (True,)*9
f = False
Use a list/dictionary or define your own class to encapsulate the stuff you're defining, but if you need all those variables you can do:
a = b = c = d = e = g = h = i = j = True
f = False
