Overview

Occasionally, python produces errors and qshell needs to be restarted to resolve the errors. This topic provides an example of the following error:

***ERROR*** <type 'exceptions.EOFError'>

Description

exception EOFError - Raised when one of the built-in functions (input() or raw_input()) hits an end-of-file condition (EOF) without reading any data. (N.B.: the file.read() and file.readline() methods return an empty string when they hit EOF.)

Workaround

Exit qshell and then reenter qshell.
