class xml.sax.handler.ErrorHandler Interface used by the parser to present error and warning messages to the application. The methods of this object control whether errors are immediately converted to exceptions or are handled in some other way.

turtle.setposition(x, y=None) Parameters: x – a number or a pair/vector of numbers y – a number or None If y is None, x must be a pair of coordinates or a Vec2D (e.g. as returned by pos()). Move turtle to an absolute position. If the pen is down, draw line. Do not change the turtle’s orientation. >>> tp = turtle.pos() >>> tp (0.00,0.00) >>> turtle.setpos(60,30) >>> turtle.pos() (60.00,30.00) >>> turtle.setpos((20,80)) >>> turtle.po

shutil.move(src, dst, copy_function=copy2) Recursively move a file or directory (src) to another location (dst) and return the destination. If the destination is an existing directory, then src is moved inside that directory. If the destination already exists but is not a directory, it may be overwritten depending on os.rename() semantics. If the destination is on the current filesystem, then os.rename() is used. Otherwise, src is copied to dst using copy_function and then removed. In case o

path The path the finder will search in.

operator.__abs__(obj) Return the absolute value of obj.

add(elem) Add element elem to the set.

sys.intern(string) Enter string in the table of “interned” strings and return the interned string – which is string itself or a copy. Interning strings is useful to gain a little performance on dictionary lookup – if the keys in a dictionary are interned, and the lookup key is interned, the key comparisons (after hashing) can be done by a pointer compare instead of a string compare. Normally, the names used in Python programs are automatically interned, and the dictionaries used to hold modu

itertools.zip_longest(*iterables, fillvalue=None) Make an iterator that aggregates elements from each of the iterables. If the iterables are of uneven length, missing values are filled-in with fillvalue. Iteration continues until the longest iterable is exhausted. Roughly equivalent to: class ZipExhausted(Exception): pass def zip_longest(*args, **kwds): # zip_longest('ABCD', 'xy', fillvalue='-') --> Ax By C- D- fillvalue = kwds.get('fillvalue') counter = len(args) - 1

date.isocalendar() Return a 3-tuple, (ISO year, ISO week number, ISO weekday). The ISO calendar is a widely used variant of the Gregorian calendar. See https://www.staff.science.uu.nl/~gent0113/calendar/isocalendar.htm for a good explanation. The ISO year consists of 52 or 53 full weeks, and where a week starts on a Monday and ends on a Sunday. The first week of an ISO year is the first (Gregorian) calendar week of a year containing a Thursday. This is called week number 1, and the ISO year
