class socketserver.TCPServer(server_address, RequestHandlerClass, bind_and_activate=True) This uses the Internet TCP protocol, which provides for continuous streams of data between the client and server. If bind_and_activate is true, the constructor automatically attempts to invoke server_bind() and server_activate(). The other parameters are passed to the BaseServer base class.

time.min The earliest representable time, time(0, 0, 0, 0).

cancel() Attempt to cancel the call. If the call is currently being executed and cannot be cancelled then the method will return False, otherwise the call will be cancelled and the method will return True.

curses.ascii.isalnum(c) Checks for an ASCII alphanumeric character; it is equivalent to isalpha(c) or isdigit(c).

body_encoding Same as header_encoding, but describes the encoding for the mail message’s body, which indeed may be different than the header encoding. Charset.SHORTEST is not allowed for body_encoding.

gettext.lgettext(message) Equivalent to gettext(), but the translation is returned in the preferred system encoding, if no other encoding was explicitly set with bind_textdomain_codeset().

assertLess(first, second, msg=None) assertLessEqual(first, second, msg=None) Test that first is respectively >, >=, < or <= than second depending on the method name. If not, the test will fail: >>> self.assertGreaterEqual(3, 4) AssertionError: "3" unexpectedly not greater than or equal to "4" New in version 3.1.

update([iterable-or-mapping]) Elements are counted from an iterable or added-in from another mapping (or counter). Like dict.update() but adds counts instead of replacing them. Also, the iterable is expected to be a sequence of elements, not a sequence of (key, value) pairs.

shutil.copyfile(src, dst, *, follow_symlinks=True) Copy the contents (no metadata) of the file named src to a file named dst and return dst. src and dst are path names given as strings. dst must be the complete target file name; look at shutil.copy() for a copy that accepts a target directory path. If src and dst specify the same file, SameFileError is raised. The destination location must be writable; otherwise, an OSError exception will be raised. If dst already exists, it will be replaced

operator.__truediv__(a, b) Return a / b where 2/3 is .66 rather than 0. This is also known as “true” division.
