ast.RShift

operators

The bitwise right shift operator >> in the op field of BinOp and AugAssign nodes.

Syntax

ast.RShift()

Shifting binds looser than addition: a >> 1 + 1 means a >> (1 + 1), and the tree has a BinOp(Add) to the right of RShift; ast.unparse adds parentheses only where they are needed. For negative numbers >> rounds down (-5 >> 1 == -3), unlike truncating division in some other languages.

Examples

import ast
n = ast.parse('a >> 1 + 1', mode='eval').body
print(type(n.op).__name__, type(n.right.op).__name__)  # → RShift Add
print(-5 >> 1)  # → -3
