Can I instrument all the functions and methods in my monolithic python script using something like typeguard.install_import_hook()?

[maspotts]

I have a large python script which I have not yet had the opportunity to refactor as a proper python project: so all the classes and methods I want to type check are inside this one script. Is there any way for me to specify something like typeguard.install_import_hook() one time, rather than decorating every single method and function? Thanks!
