os.get_terminal_size() fails with () or (0) or (1)

shutil.sys fails calling it with (sys.__stdout__.fileno())
 because sys.__stdout__ is type None

The 3.5 branch only gets security fixes at this point. Consider upgrading to 3.6.

That said, this shouldn't be a problem with shutil.get_terminal_size() in 3.5. It handles AttributeError, ValueError, and OSError by returning the `fallback` size. And it's expected that `os.get_terminal_size(1)` will fail if there's no attached console.

Thanks for the report. I agree with Eryk. os.get_terminal_size() is a low-level function. shutil.get_terminal_size() should be used as documented at https://docs.python.org/3/library/os.html#os.get_terminal_size

    shutil.get_terminal_size() is the high-level function which should
    normally be used, os.get_terminal_size is the low-level
    implementation.

Thankyou for clearing that up!
