Language reference, mostly section 5.3 Primaries
call ::=
primary "(" [argument_list [","]
| expression genexpr_for] ")"
primary ::=
atom | attributeref
| subscription | slicing | call
attributeref ::=
primary "." identifier
atom ::=
identifier | literal | enclosure
That shows fairly well how the classname.functioname bit works (it is an
attributeref which is a primary which forms the first part of a call),
but you'll have to wade through a fair bit of the grammar to show that
argument_list can be an identifier.
argument_list ::=
positional_arguments ["," keyword_arguments]
["," "*" expression]
["," "**" expression]
| keyword_arguments ["," "*" expression]
["," "**" expression]
| "*" expression ["," "**" expression]
| "**" expression
positional_arguments ::=
expression ("," expression)*
... and so on ...
