hasattr(object, name) The arguments are an object and a string. The result is True if the string is the name of one of the object’s attributes, False if not. (This is implemented by calling getattr(object, name) and seeing whether it raises an AttributeError or not.)

get_content_disposition() Return the lowercased value (without parameters) of the message’s Content-Disposition header if it has one, or None. The possible values for this method are inline, attachment or None if the message follows RFC 2183. New in version 3.5.

math.acosh(x) Return the inverse hyperbolic cosine of x.

codecs.register(search_function) Register a codec search function. Search functions are expected to take one argument, being the encoding name in all lower case letters, and return a CodecInfo object. In case a search function cannot find a given encoding, it should return None. Note Search function registration is not currently reversible, which may cause problems in some cases, such as unit testing or module reloading.

str.strip([chars]) Return a copy of the string with the leading and trailing characters removed. The chars argument is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a prefix or suffix; rather, all combinations of its values are stripped: >>> ' spacious '.strip() 'spacious' >>> 'www.example.com'.strip('cmowz.') 'example' The outermost leading and trailing chars a

Repr.maxdeque Repr.maxarray Limits on the number of entries represented for the named object type. The default is 4 for maxdict, 5 for maxarray, and 6 for the others.

SSLSocket.context The SSLContext object this SSL socket is tied to. If the SSL socket was created using the top-level wrap_socket() function (rather than SSLContext.wrap_socket()), this is a custom context object created for this SSL socket. New in version 3.2.

class symtable.Function A namespace for a function or method. This class inherits SymbolTable. get_parameters() Return a tuple containing names of parameters to this function. get_locals() Return a tuple containing names of locals in this function. get_globals() Return a tuple containing names of globals in this function. get_frees() Return a tuple containing names of free variables in this function.

element_names() Returns the list of elements defined in the current theme.

attach(payload) Add the given payload to the current payload, which must be None or a list of Message objects before the call. After the call, the payload will always be a list of Message objects. If you want to set the payload to a scalar object (e.g. a string), use set_payload() instead.
