Names for built-in exceptions and functions and a number of constants are found
|
|
|
|
|
in a separate symbol table. This table is searched last when the interpreter
|
|
|
|
|
looks up the meaning of a name, so local and global user-defined names can
|
|
|
|
|
override built-in names. Built-in types are described together here for easy

Optimize PyList_AsTuple(). Improve cache performance by doing the
pointer copy and object increment in one pass. For small lists,
save the overhead of the call to memcpy() -- this comes up in
calls like f(*listcomp).

The tables in this chapter document the priorities of operators by listing them
|
|
|
|
|
in order of ascending priority (within a table) and grouping operators that have
|
|
|
|
|
the same priority in the same box. Binary operators of the same priority group
|
|
|
|
|
from left to right. (Unary operators group from right to left, but there you
|
|
|
|
|
have no real choice.) See :ref:`operator-summary` for the complete picture on
|
|
|
|
|
operator priorities.
