hash.copy() Return a copy (“clone”) of the hash object. This can be used to efficiently compute the digests of data sharing a common initial substring.

get_visible() Return an Message instance whose headers are the message’s visible headers and whose body is empty.

CookiePolicy.set_ok(cookie, request) Return boolean value indicating whether cookie should be accepted from server. cookie is a Cookie instance. request is an object implementing the interface defined by the documentation for CookieJar.extract_cookies().

get_symbols() Return a list of Symbol instances for names in the table.

tb_locals If set to true then local variables will be shown in tracebacks. New in version 3.5.

setdefault(key[, default]) If key is in the dictionary, return its value. If not, insert key with a value of default and return default. default defaults to None.

datetime.utctimetuple() If datetime instance d is naive, this is the same as d.timetuple() except that tm_isdst is forced to 0 regardless of what d.dst() returns. DST is never in effect for a UTC time. If d is aware, d is normalized to UTC time, by subtracting d.utcoffset(), and a time.struct_time for the normalized time is returned. tm_isdst is forced to 0. Note that an OverflowError may be raised if d.year was MINYEAR or MAXYEAR and UTC adjustment spills over a year boundary.

symtable.symtable(code, filename, compile_type) Return the toplevel SymbolTable for the Python source code. filename is the name of the file containing the code. compile_type is like the mode argument to compile().

done() Return True if the call was successfully cancelled or finished running.

remove_done_callback(fn) Remove all instances of a callback from the “call when done” list. Returns the number of callbacks removed.
