traceback.print_exception(etype, value, tb, limit=None, file=None, chain=True) Print exception information and stack trace entries from traceback object tb to file. This differs from print_tb() in the following ways: if tb is not None, it prints a header Traceback (most recent call last): it prints the exception etype and value after the stack trace if etype is SyntaxError and value has the appropriate format, it prints the line where the syntax error occurred with a caret indicating the ap

class mailbox.MHMessage(message=None) A message with MH-specific behaviors. Parameter message has the same meaning as with the Message constructor. MH messages do not support marks or flags in the traditional sense, but they do support sequences, which are logical groupings of arbitrary messages. Some mail reading programs (although not the standard mh and nmh) use sequences in much the same way flags are used with other formats, as follows: Sequence Explanation unseen Not read, but previous

Path.mkdir(mode=0o777, parents=False, exist_ok=False) Create a new directory at this given path. If mode is given, it is combined with the process’ umask value to determine the file mode and access flags. If the path already exists, FileExistsError is raised. If parents is true, any missing parents of this path are created as needed; they are created with the default permissions without taking mode into account (mimicking the POSIX mkdir -p command). If parents is false (the default), a miss

ErrorHandler.error(exception) Called when the parser encounters a recoverable error. If this method does not raise an exception, parsing may continue, but further document information should not be expected by the application. Allowing the parser to continue may allow additional errors to be discovered in the input document.

math.isclose(a, b, *, rel_tol=1e-09, abs_tol=0.0) Return True if the values a and b are close to each other and False otherwise. Whether or not two values are considered close is determined according to given absolute and relative tolerances. rel_tol is the relative tolerance – it is the maximum allowed difference between a and b, relative to the larger absolute value of a or b. For example, to set a tolerance of 5%, pass rel_tol=0.05. The default tolerance is 1e-09, which assures that the t

Logger.hasHandlers() Checks to see if this logger has any handlers configured. This is done by looking for handlers in this logger and its parents in the logger hierarchy. Returns True if a handler was found, else False. The method stops searching up the hierarchy whenever a logger with the ‘propagate’ attribute set to False is found - that will be the last logger which is checked for the existence of handlers. New in version 3.2.

maxsize Number of items allowed in the queue.

classmethod int.from_bytes(bytes, byteorder, *, signed=False) Return the integer represented by the given array of bytes. >>> int.from_bytes(b'\x00\x10', byteorder='big') 16 >>> int.from_bytes(b'\x00\x10', byteorder='little') 4096 >>> int.from_bytes(b'\xfc\x00', byteorder='big', signed=True) -1024 >>> int.from_bytes(b'\xfc\x00', byteorder='big', signed=False) 64512 >>> int.from_bytes([255, 0, 0], byteorder='big') 16711680 The argument bytes must

curses.raw() Enter raw mode. In raw mode, normal line buffering and processing of interrupt, quit, suspend, and flow control keys are turned off; characters are presented to curses input functions one by one.
