itertools.dropwhile(predicate, iterable) Make an iterator that drops elements from the iterable as long as the predicate is true; afterwards, returns every element. Note, the iterator does not produce any output until the predicate first becomes false, so it may have a lengthy start-up time. Roughly equivalent to: def dropwhile(predicate, iterable): # dropwhile(lambda x: x<5, [1,4,6,4,1]) --> 6 4 1 iterable = iter(iterable) for x in iterable: if not predicate(x):

turtle.stamp() Stamp a copy of the turtle shape onto the canvas at the current turtle position. Return a stamp_id for that stamp, which can be used to delete it by calling clearstamp(stamp_id). >>> turtle.color("blue") >>> turtle.stamp() 11 >>> turtle.fd(50)

ssl.OP_NO_TLSv1_1 Prevents a TLSv1.1 connection. This option is only applicable in conjunction with PROTOCOL_SSLv23. It prevents the peers from choosing TLSv1.1 as the protocol version. Available only with openssl version 1.0.1+. New in version 3.4.

run(cmd, globals=None, locals=None) Debug a statement executed via the exec() function. globals defaults to __main__.__dict__, locals defaults to globals.

modulefinder.ReplacePackage(oldname, newname) Allows specifying that the module named oldname is in fact the package named newname.

InteractiveInterpreter.runsource(source, filename="", symbol="single") Compile and run some source in the interpreter. Arguments are the same as for compile_command(); the default for filename is '<input>', and for symbol is 'single'. One several things can happen: The input is incorrect; compile_command() raised an exception (SyntaxError or OverflowError). A syntax traceback will be printed by calling the showsyntaxerror() method. runsource() returns False. The input is incomplete, an

socket.share(process_id) Duplicate a socket and prepare it for sharing with a target process. The target process must be provided with process_id. The resulting bytes object can then be passed to the target process using some form of interprocess communication and the socket can be recreated there using fromshare(). Once this method has been called, it is safe to close the socket since the operating system has already duplicated it for the target process. Availability: Windows. New in versi

class urllib.request.UnknownHandler A catch-all class to handle unknown URLs.

str.isalnum() Return true if all characters in the string are alphanumeric and there is at least one character, false otherwise. A character c is alphanumeric if one of the following returns True: c.isalpha(), c.isdecimal(), c.isdigit(), or c.isnumeric().

handle_write() Called when the asynchronous loop detects that a writable socket can be written. Often this method will implement the necessary buffering for performance. For example: def handle_write(self): sent = self.send(self.buffer) self.buffer = self.buffer[sent:]
