langchain_experimental.pal_chain.base.PALValidationΒΆ

class langchain_experimental.pal_chain.base.PALValidation(solution_expression_name: Optional[str] = None, solution_expression_type: Optional[type] = None, allow_imports: bool = False, allow_command_exec: bool = False)[source]ΒΆ

Validation for PAL generated code.

Initialize a PALValidation instance.

Parameters
  • solution_expression_name (str) – Name of the expected solution expression. If passed, solution_expression_type must be passed as well.

  • solution_expression_type (str) – AST type of the expected solution expression. If passed, solution_expression_name must be passed as well. Must be one of PALValidation.SOLUTION_EXPRESSION_TYPE_FUNCTION, PALValidation.SOLUTION_EXPRESSION_TYPE_VARIABLE.

  • allow_imports (bool) – Allow import statements.

  • allow_command_exec (bool) – Allow using known command execution functions.
