COLUMNS is a shell variable (updated whenever the window size changes), that usually isn't exported to programs. Therefore checking for COLUMNS in sys.environ will not work in the majority of cases. The proper check is to use the TIOCGWINSZ ioctl on stdout. Why COLUMNS is not exported? Because it can change during the lifetime of a program. Therefore it is better to use the dynamic ioctl.
