What are you trying to do? Share the contents of JSBSim_1.py or least the relevant sections that are trying to use FGRocket.

its appears in c++ code, but not in python of this attribute,

Not every single C++ class and method is exposed 1 for 1 in the python API.

Hence my question:

What are you trying to do? Share the contents of JSBSim_1.py or least the relevant sections that are trying to use FGRocket.

If you share that sort of information we can potentially help in terms of possibly pointing you to an alternative API to achieve the same goal, or if there is a good reason for exposing something via the python API then we can look at that as well.

But we need more information.

import jsbsim

jsbsim.FGRocket('..\')

that is all

import jsbsim

jsbsim.FGRocket('..\')

that is all

Even in C++, FGRocket is not meant to be used in isolation and there is no constructor of FGRocket that takes a string as an input so don't expect this code to work at all.

The simplest example of using a rocket with JSBSim is:

import jsbsim

fdm = jsbsim.FGFDMExec(None)  # Use JSBSim default aircraft data.
fdm.load_script('scripts/J2461.xml')
fdm.run_ic()

while fdm.run():
  pass

That's not enough information for me to make any useful comments or suggestions.
