math.asinh(x) Return the inverse hyperbolic sine of x.

lzma.open(filename, mode="rb", *, format=None, check=-1, preset=None, filters=None, encoding=None, errors=None, newline=None) Open an LZMA-compressed file in binary or text mode, returning a file object. The filename argument can be either an actual file name (given as a str or bytes object), in which case the named file is opened, or it can be an existing file object to read from or write to. The mode argument can be any of "r", "rb", "w", "wb", "x", "xb", "a" or "ab" for binary mode, or "r

sort(*, key=None, reverse=None) This method sorts the list in place, using only < comparisons between items. Exceptions are not suppressed - if any comparison operations fail, the entire sort operation will fail (and the list will likely be left in a partially modified state). sort() accepts two arguments that can only be passed by keyword (keyword-only arguments): key specifies a function of one argument that is used to extract a comparison key from each list element (for example, key=st

column(column, option=None, **kw) Query or modify the options for the specified column. If kw is not given, returns a dict of the column option values. If option is specified then the value for that option is returned. Otherwise, sets the options to the corresponding values. The valid options/values are: id Returns the column name. This is a read-only option. anchor: One of the standard Tk anchor values. Specifies how the text in this column should be aligned with respect to the cell.

class xmlrpc.server.SimpleXMLRPCServer(addr, requestHandler=SimpleXMLRPCRequestHandler, logRequests=True, allow_none=False, encoding=None, bind_and_activate=True, use_builtin_types=False) Create a new server instance. This class provides methods for registration of functions that can be called by the XML-RPC protocol. The requestHandler parameter should be a factory for request handler instances; it defaults to SimpleXMLRPCRequestHandler. The addr and requestHandler parameters are passed to

Node.unlink() Break internal references within the DOM so that it will be garbage collected on versions of Python without cyclic GC. Even when cyclic GC is available, using this can make large amounts of memory available sooner, so calling this on DOM objects as soon as they are no longer needed is good practice. This only needs to be called on the Document object, but may be called on child nodes to discard children of that node. You can avoid calling this method explicitly by using the wit

coroutine AbstractEventLoop.sock_recv(sock, nbytes) Receive data from the socket. Modeled after blocking socket.socket.recv() method. The return value is a bytes object representing the data received. The maximum amount of data to be received at once is specified by nbytes. With SelectorEventLoop event loop, the socket sock must be non-blocking. This method is a coroutine.

test.support.verbose True when verbose output is enabled. Should be checked when more detailed information is desired about a running test. verbose is set by test.regrtest.

class http.cookiejar.DefaultCookiePolicy(blocked_domains=None, allowed_domains=None, netscape=True, rfc2965=False, rfc2109_as_netscape=None, hide_cookie2=False, strict_domain=False, strict_rfc2965_unverifiable=True, strict_ns_unverifiable=False, strict_ns_domain=DefaultCookiePolicy.DomainLiberal, strict_ns_set_initial_dollar=False, strict_ns_set_path=False) Constructor arguments should be passed as keyword arguments only. blocked_domains is a sequence of domain names that we never accept coo

set_from(from_, time_=None) Set the “From ” line to from_, which should be specified without a leading “From ” or trailing newline. For convenience, time_ may be specified and will be formatted appropriately and appended to from_. If time_ is specified, it should be a time.struct_time instance, a tuple suitable for passing to time.strftime(), or True (to use time.gmtime()).
