You don't import a file, you import a module. And a module name is an
Identifiers must begin with a letter or underscore.
(Standalone scripts that aren't supposed to be imported don't have to obey
this rule, like 2to3.py)

It's not a bug. Suppose you have a file '1.py' and you could write:
x = 1
Does x refer to the integer 1 or the module 1?

You might use a prefix in all these modules. Or just an _ in front of the
ones that start with a number. But remember that a module name must obey
both your filesystem rules for file names and Python rules for
identifiers: letters A-Z (unless you're using Python 3), digits, _.
