Python's interactive mode works on the principle of REPL (Read - Evaluate - Print - Loop). The code module in Python's standard library provides classes nd convenience functions to set up REPL environment from within Python script.Following two classes are defined in code module:InteractiveInterpreter: This class deals with parsing and interpreter state (the user’s namespace)InteractiveConsole: Closely emulate the behavior of the interactive Python interpreter.Two convenience functions in the module are:interact(): Convenience function to run a read-eval-print loop.compile_command(): This function is useful for programs that want to emulate Python’s interpreter main loop (the REPL).Interactive Interpreter methodsrunsource(): Compile and run some source ...

When you want to add to the module search path for a specific package and work with resources included in a package, you need to use pkgutil module from Python library. It includes functions for changing the import rules for Python packages. It is also possible to load non-code resources from files distributed within a package.extend_path(path, name)Extend the search path for the modules which comprise a package. Intended use is to place the following code in a package’s __init__.pyimport pkgutil __path__ = pkgutil.extend_path(__path__, __name__)extend_path() scans sys.path for directories that include a subdirectory named for the package given as the second ...

The poolib module from Python's standard library defines POP3 and POP3_SSL classes. POP3 class encapsulates a connection to a POP3 server and implements the protocol as defined in RFC 1939. POP3_SSL classsupports POP3 servers that use SSL as an underlying protocol layer.POP3 protocolis obsolescent as its implementation quality of POP3 servers is quite poor. If your mailserver supports IMAP, it is recommended to use the imaplib.IMAP4 class.Both classes have following methods defined −getwelcome()Returns the greeting string sent by the POP3 server.user(username)Send user command, response should indicate that a password is required.pass_(password)Send password.Stat()Get mailbox status. The result contains 2 integers: (message ... Read More
