That's not quite right. It is the open brace/bracket/parenthesis that
tells Python to continue the line; the comma is not part of it. For
example, this works:
In [17]: a=1,2,3,4
but inserting a newline, even after a comma, breaks it into two statements:
In [24]: a=1,2,
In [25]: 3,4
Out[25]: (3, 4)
In [26]: a
Out[26]: (1, 2)
OTOH, if there is an open bracket, the comma can come on the next line:
In [21]: a=[1
....: ,2,3,4]
In [22]: a
Out[22]: [1, 2, 3, 4]
