3.4. Context Expressions

3.4.1. Unary Expressions

PyTypeObject CpUnaryExpr_Type

The type object for the CpUnaryExprObject class.

type CpUnaryExprObject

A simple unary expression (from Python).

This is a helper class to support lazy evaluation of unary expressions while parsing data.

CpUnaryExprObject *CpUnaryExpr_New(int op, PyObject *value)

Return value: New reference.

Creates a new unary expression. Returns NULL if an error occurs. The op argument should be one of the CpUnaryExpr constants listed below.

int CpUnaryExpr_OpNeg = 1

int CpUnaryExpr_OpNot = 2

int CpUnaryExpr_OpPos = 3

3.4.2. Binary Expressions

PyTypeObject CpBinaryExpr_Type

The type object for the CpBinaryExprObject class.

type CpBinaryExprObject

A simple binary expression (from Python).

This is a helper class to support lazy evaluation of binary expressions while parsing data.

CpBinaryExprObject *CpBinaryExpr_New(int op, PyObject *left, PyObject *right)

Return value: New reference.

Creates a new binary expression. Returns NULL if an error occurs. The op argument should be one of the CpBinaryExpr constants listed below.

int CpBinaryExpr_Op_LT = 0

int CpBinaryExpr_Op_LE = 1

int CpBinaryExpr_Op_EQ = 2

int CpBinaryExpr_Op_NE = 3

int CpBinaryExpr_Op_GT = 4

int CpBinaryExpr_Op_GE = 5

int CpBinaryExpr_OpAdd = 6

int CpBinaryExpr_OpSub = 7

int CpBinaryExpr_OpMul = 8

int CpBinaryExpr_OpFloorDiv = 9

int CpBinaryExpr_OpTrueDiv = 10

int CpBinaryExpr_OpMod = 11

int CpBinaryExpr_OpPow = 12

int CpBinaryExpr_OpMatMul = 13

int CpBinaryExpr_OpAnd = 14

int CpBinaryExpr_OpOr = 15

int CpBinaryExpr_OpBitXor = 16

int CpBinaryExpr_OpBitAnd = 17

int CpBinaryExpr_OpBitOr = 18

int CpBinaryExpr_OpLShift = 19

int CpBinaryExpr_OpRShift = 20

Note that the first six operations store the same value as defined by Python, minimizing the effort to translate *_richcmp calls into this enum.
