Hi Xiao,
This is a really basic question and I really recommend a good tutorial. Maybe this one https://www.knowledgehut.com/blog/programming/run-python-scripts?
But in short, when you ran /usr/local/bin/python3 you entered the interactive python environment. Only python commands will now work. You can exit by pressing Ctrl-Z or by typing exit(). Type *import modeller* to is if the package is installed.
Best, Ajasja
