The value of each symbol is the corresponding integer value. https://docs.python.org/2/library/errno.html The names and descriptions are borrowed from linux/include/errno.h, which should be pretty all-inclusive. errno.errorcode¶ Dictionary providing a mapping from the errno value to the string name in the underlying system. For instance, errno.errorcode[errno.EPERM] maps to 'EPERM'. To translate a numeric error code to an error message, python exception use os.strerror().
