help(tuple) gives me this, which does not mention ',' either.
Help on class tuple in module __builtin__:
class tuple(object)
| tuple() -> empty tuple
| tuple(iterable) -> tuple initialized from iterable's items
|
| If the argument is a tuple, the return value is the same object.

| __add__(...)
| x.__add__(y) <==> x+y
|
| __contains__(...)
| x.__contains__(y) <==> y in x

| __eq__(...)
| x.__eq__(y) <==> x==y
|
| __ge__(...)
| x.__ge__(y) <==> x>=y
|
| __getattribute__(...)
| x.__getattribute__('name') <==> x.name
|
| __getitem__(...)
| x.__getitem__(y) <==> x[y]
|
| __getnewargs__(...)
|
| __getslice__(...)
| x.__getslice__(i, j) <==> x[i:j]

| Use of negative indices is not supported.

|
| __repr__(...)
| x.__repr__() <==> repr(x)
|
| __rmul__(...)
| x.__rmul__(n) <==> n*x
|
| count(...)
| T.count(value) -> integer -- return number of occurrences of value
|
| index(...)
| T.index(value, [start, [stop]]) -> integer -- return first
index of value.
| Raises ValueError if the value is not present.
