How to check if a path *could* be a legal path?

Hi,

I have a string.
This string is to be used as a path for a new file.
I would like to check if this string *could be* a valid file name,
*before* I try to create the file itself.
In other words, I would like to know whether some string violates the
underlying OS's policies (or maybe some more restriced policies, but
portable) considering file paths.

Example:

1.
s = 'C:\file.txt'

the above is potentially a valid path on my system.

2.
s = 'cc:/^- =#jk\kj+.+?! :-)'

the above is rather invalid and I would like to check it somehow before
I even try to create the file.

Does the Python library contain a functionality that allows to achieve
this goal?

There's no single set of rules that can be applied to a string to inform you whether it's a valid path. ...
