Sounds like you are running in the interactive mode; ie opened python
session interactively in a command prompt and typed
In which case;
help(clr) # would yield:
Help on module clr:
AddReference = <CLRModuleFunction 'AddReference'>
FindAssembly = <CLRModuleFunction 'FindAssembly'>
ListAssemblies = <CLRModuleFunction 'ListAssemblies'>
getPreload = <CLRModuleFunction 'getPreload'>
setPreload = <CLRModuleFunction 'setPreload'>
The Preload flag is set to True in interactive mode. Its function is to
load the entire namespace of the default assemblies into the
interpreter's namespace (mostly for debugging).
Please confirm that
clears up your concern.
