python解析.pyd文件

有的时候，为了对python文件进行加密，会把python模块编译成.pyd文件，供其他人调用。拿到一个.pyd文件，在没有文档说明的情况下，可以试试查看模块内的一些函数和类的用法。
首先 import XXX（pyd的文件名)
然后直接
print(dir(XXX))
print(help(xxx))

其中dir( ) 列出了属性和方法
而hlep()直接列出了其中的函数以及参数，并且是源码的函数名和类型，非常直观。
例如我这里的一个例子，输出如下：

['RC', '__doc__', '__file__', '__loader__', '__name__', '__package__', '__spec__', 'call_func', 'collision_recover', 'disable_robot', 'drag_mode_enable', 'enable_robot', 'get_analog_input', 'get_analog_output', 'get_collision_level', 'get_current_line', 'get_digital_input', 'get_digital_output', 'get_joint_position', 'get_loaded_program', 'get_payload', 'get_program_state', 'get_rapidrate', 'get_robot_state', 'get_sdk_version', 'get_tcp_position', 'get_tool_id', 'get_user_frame_id', 'is_extio_running', 'is_in_collision', 'is_in_drag_mode', 'is_in_pos', 'is_on_limit', 'jog', 'jog_stop', 'joint_move', 'kine_forward', 'kine_inverse', 'linear_move', 'login', 'logout', 'power_off', 'power_on', 'program_abort', 'program_load', 'program_pause', 'program_resume', 'program_run', 'quaternion_to_rot_matrix', 'rot_matrix_to_quaternion', 'rot_matrix_to_rpy', 'rpy_to_rot_matrix', 'servo_j', 'servo_move_enable', 'servo_p', 'set_analog_output', 'set_collision_level', 'set_digital_output', 'set_error_handler', 'set_payload', 'set_rapidrate', 'set_tool_data', 'set_tool_id', 'set_user_frame_data', 'set_user_frame_id', 'shut_down', 'torque_control_enable', 'torque_feedforward']
