handling open failures

[Skaperen]

do all open() failures always cause an exception in the open() call and never just return a None or something else that could cause an exception later on? i'm wanting to move some failure handling to with open() that could be awkward if it needs to also check for returned errors.

The doc says

Output:
Open file and return a corresponding file object. If the file cannot be opened, an OSError is raised.

Why not believe it?
