Python node_to_string Examples

Example #1

def test_compare():
    expr = "(x < 0)"
    node = parse_expression(expr)
    assert expr == node_to_string(node)

    expr = "((x < 0) >= 6)"
    node = parse_expression(expr)
    assert expr == node_to_string(node)

    expr = "(x // 10)"
    node = parse_expression(expr)
    assert expr == node_to_string(node)

Example #2

def test_binary_ops(op):
    expression = f'(a {op["code"]} b)'
    node = parse_expression(expression)
    assert node_to_string(node) == expression
    validate_expression(expression, {'a', 'b'})

Example #3

def test_unary_ops(op):
    expression = f'{op["code"]}a'
    node = parse_expression(expression)
    assert node_to_string(node) == expression
