[Tutor] Importing module - file system requests

[Bernard Lebel]

Hello,

When I import a module in Python, I see that 6 file system operation
are being made. All requests are for opening.
I know very well what are the .py and and .pyc files. But I'm not so
sure what are .pyd and .pyw, and why it's looking for a dll. Anyone
can shed some light on this?

Also, if I have a .pyd version of modules, will it skip the other requests?

Here are the requests, in order:
file directory
.pyd file
.dll file
.py file
.pyw file
.pyc file



Thanks
Bernard
