TarFile.add(name, arcname=None, recursive=True, exclude=None, *, filter=None) Add the file name to the archive. name may be any type of file (directory, fifo, symbolic link, etc.). If given, arcname specifies an alternative name for the file in the archive. Directories are added recursively by default. This can be avoided by setting recursive to False. If exclude is given, it must be a function that takes one filename argument and returns a boolean value. Depending on this value the respecti

class random.SystemRandom([seed]) Class that uses the os.urandom() function for generating random numbers from sources provided by the operating system. Not available on all systems. Does not rely on software state, and sequences are not reproducible. Accordingly, the seed() method has no effect and is ignored. The getstate() and setstate() methods raise NotImplementedError if called.

time.perf_counter() Return the value (in fractional seconds) of a performance counter, i.e. a clock with the highest available resolution to measure a short duration. It does include time elapsed during sleep and is system-wide. The reference point of the returned value is undefined, so that only the difference between the results of consecutive calls is valid. New in version 3.3.

shlex.split(s, comments=False, posix=True) Split the string s using shell-like syntax. If comments is False (the default), the parsing of comments in the given string will be disabled (setting the commenters attribute of the shlex instance to the empty string). This function operates in POSIX mode by default, but uses non-POSIX mode if the posix argument is false. Note Since the split() function instantiates a shlex instance, passing None for s will read the string to split from standard in

monthdatescalendar(year, month) Return a list of the weeks in the month month of the year as full weeks. Weeks are lists of seven datetime.date objects.

yeardayscalendar(year, width=3) Return the data for the specified year ready for formatting (similar to yeardatescalendar()). Entries in the week lists are day numbers. Day numbers outside this month are zero.

exception TypeError Raised when an operation or function is applied to an object of inappropriate type. The associated value is a string giving details about the type mismatch.

shlex.instream The input stream from which this shlex instance is reading characters.

has_children() Return True if the block has nested namespaces within it. These can be obtained with get_children().

turtle.dot(size=None, *color) Parameters: size – an integer >= 1 (if given) color – a colorstring or a numeric color tuple Draw a circular dot with diameter size, using color. If size is not given, the maximum of pensize+4 and 2*pensize is used. >>> turtle.home() >>> turtle.dot() >>> turtle.fd(50); turtle.dot(20, "blue"); turtle.fd(50) >>> turtle.position() (100.00,-0.00) >>> turtle.heading() 0.0
