What's unexpected about it? Child processes inherit all of the open file
descriptors of their parent. A socket is simply another open file
descriptor. When your parent process exits, your child still holds a valid,
open file descriptor.

The open file descriptor/socket shouldn't "move" between processes when you

Depending on the size of your file, you can just use file.readlines.
Note that file.readlines is going to read the entire file into memory,

You'll see the same behavior if you attempt to add an attribute to an
instance of object as well.
>>> object().t = 5
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'object' object has no attribute 't'

You'll have to build your own iterator or wrap the generator obje

You can pull it out of f.func_code.co_varnames, but I don't believe
