Built-in Module

% If implemented in C

The
\code
{
operator
}
module exports a set of functions implemented in C
corresponding to the intrinsic operators of Python. For example,
{}
\code
{
operator.add(x, y)
}
is equivalent to the expression x+y. The
function names are those used for special class methods; variants without
leading and trailing '
\_\_
' are also provided for convenience.
The
\code
{
operator
}
module defines the following functions:
