exception configparser.Error Base class for all other configparser exceptions.

select.select(rlist, wlist, xlist[, timeout]) This is a straightforward interface to the Unix select() system call. The first three arguments are sequences of ‘waitable objects’: either integers representing file descriptors or objects with a parameterless method named fileno() returning such an integer: rlist: wait until ready for reading wlist: wait until ready for writing xlist: wait for an “exceptional condition” (see the manual page for what your system considers such a condition)

ArgumentParser.error(message) This method prints a usage message including the message to the standard error and terminates the program with a status code of 2.

format_exception_only() Format the exception part of the traceback. The return value is a generator of strings, each ending in a newline. Normally, the generator emits a single string; however, for SyntaxError exceptions, it emits several lines that (when printed) display detailed information about where the syntax error occurred. The message indicating which exception occurred is always the last string in the output.

AbstractEventLoop.call_later(delay, callback, *args) Arrange for the callback to be called after the given delay seconds (either an int or float). An instance of asyncio.Handle is returned, which can be used to cancel the callback. callback will be called exactly once per call to call_later(). If two callbacks are scheduled for exactly the same time, it is undefined which will be called first. The optional positional args will be passed to the callback when it is called. If you want the call

sys._xoptions A dictionary of the various implementation-specific flags passed through the -X command-line option. Option names are either mapped to their values, if given explicitly, or to True. Example: $ ./python -Xa=b -Xc Python 3.2a3+ (py3k, Oct 16 2010, 20:14:50) [GCC 4.4.3] on linux2 Type "help", "copyright", "credits" or "license" for more information. >>> import sys >>> sys._xoptions {'a': 'b', 'c': True} CPython implementation detail: This is a CPython-specific

xml.dom.minidom.parse(filename_or_file, parser=None, bufsize=None) Return a Document from the given input. filename_or_file may be either a file name, or a file-like object. parser, if given, must be a SAX2 parser object. This function will change the document handler of the parser and activate namespace support; other parser configuration (like setting an entity resolver) must have been done in advance.

addcomponent(poly, fill, outline=None) Parameters: poly – a polygon, i.e. a tuple of pairs of numbers fill – a color the poly will be filled with outline – a color for the poly’s outline (if given) Example: >>> poly = ((0,0),(10,-5),(0,10),(-10,-5)) >>> s = Shape("compound") >>> s.addcomponent(poly, "red", "blue") >>> # ... add more components and then use register_shape() See Compound shapes.

int.bit_length() Return the number of bits necessary to represent an integer in binary, excluding the sign and leading zeros: >>> n = -37 >>> bin(n) '-0b100101' >>> n.bit_length() 6 More precisely, if x is nonzero, then x.bit_length() is the unique positive integer k such that 2**(k-1) <= abs(x) < 2**k. Equivalently, when abs(x) is small enough to have a correctly rounded logarithm, then k = 1 + int(log(abs(x), 2)). If x is zero, then x.bit_length() returns

class bz2.BZ2Decompressor Create a new decompressor object. This object may be used to decompress data incrementally. For one-shot compression, use the decompress() function instead. Note This class does not transparently handle inputs containing multiple compressed streams, unlike decompress() and BZ2File. If you need to decompress a multi-stream input with BZ2Decompressor, you must use a new decompressor for each stream. decompress(data, max_length=-1) Decompress data (a bytes-like ob
