Parsing functions with multiple arguments

[Zelatrix]

I have managed to successfully implement functions with no arguments into my parser and they parser correctly, The way I have it so far also allows me to parse functions with a single argument. But I am not sure how to parse functions with multiple arguments. The code I have for this at the moment is the following:

@self.pg.production('arg : type expr')
 def typed_arg(p):
   return [p[0], p[1]]
     
# Argument list for functions:
# function f(int x) {
#   print(x);
# }

@self.pg.production('arg_list : arg COMMA arg_list')
def arg_list(p):
  return [p[0]] + p[2]

@self.pg.production('arg_list : ')
def empty_args(p):
  return []

Can you explain what's going on here?
