False The false value of the bool type. Assignments to False are illegal and raise a SyntaxError.

This module makes available standard errno system symbols. The value of each symbol is the corresponding integer value. 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, use os.strerror(). Of the following lis

exception EOFError Raised when the input() function hits an end-of-file condition (EOF) without reading any data. (N.B.: the io.IOBase.read() and io.IOBase.readline() methods return an empty string when they hit EOF.)

exception Exception All built-in, non-system-exiting exceptions are derived from this class. All user-defined exceptions should also be derived from this class.

eval(expression, globals=None, locals=None) The arguments are a string and optional globals and locals. If provided, globals must be a dictionary. If provided, locals can be any mapping object. The expression argument is parsed and evaluated as a Python expression (technically speaking, a condition list) using the globals and locals dictionaries as global and local namespace. If the globals dictionary is present and lacks ‘__builtins__’, the current globals are copied into globals before exp

enumerate(iterable, start=0) Return an enumerate object. iterable must be a sequence, an iterator, or some other object which supports iteration. The __next__() method of the iterator returned by enumerate() returns a tuple containing a count (from start which defaults to 0) and the values obtained from iterating over iterable. >>> seasons = ['Spring', 'Summer', 'Fall', 'Winter'] >>> list(enumerate(seasons)) [(0, 'Spring'), (1, 'Summer'), (2, 'Fall'), (3, 'Winter')] >>

class enum.IntEnum Base class for creating enumerated constants that are also subclasses of int.

class enum.Enum Base class for creating enumerated constants. See section Functional API for an alternate construction syntax.

exception EnvironmentError

enum.unique() Enum class decorator that ensures only one name is bound to any one value.
