This method always returns str object. str wrapped returns unwrapped, bytes or bytearray wrapped returns str converted, dict wrapped returns \"key=value\" pairs joined with \"&\".\r\n* foreach(f)\r\n    Applies a given f to all elements.\r\n* filter(pred)\r\n    Selects all elements which satisfy a given predicate.\r\n* map(f)\r\n    Builds a new collection by applying a given f.\r\n* forall(pred)\r\n    True if all elements satisfy a given predicate.\r\n* forany(pred)\r\n    True if any elements satisfy a given predicate.\r\n* dropwhile(pred)\r\n    Drops longest prefix of elements that satisfy a given predicate.\r\n* dropright(pred)\r\n    Drops longest suffix of elements that satisfy a given predicate.\r\n* takwhile(pred)\r\n    Takes longest prefix of elements that satisfy a given predicate.\r\n* takeright(pred)\r\n    Takes longest suffix of elements that satisfy a given predicate.\r\n* mkstring(joiner=\"\")\r\n    Returns wrapped str object using a joiner string.\r\n* counts(pred=lambda x: True)\r\n    Counts the number of elements that satisfy a given predicate.\r\n* contains(key)\r\n    Tests whether this wrapped object contains a given key as an element.\r\n* reduce(f)\r\n    Returns a value(not wrapped) using a given f.\r\n    \r\niterator specific API\r\n^^^^^^^^^^^^^^^^^^^^^\r\n* tolist\r\n    Returns a new list wrapped.\r\n* totuple\r\n    Returns a new tuple wrapped.\r\n* toset\r\n    Returns a new set wrapped.\r\n    \r\nstr, bytes, bytearray specific API\r\n^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\r\n* reverse\r\n    Returns a new reversed str wrapped.\r\n\r\nseq specific API\r\n^^^^^^^^^^^^^^^^\r\n* accumulate(f)\r\n    Returns a seq of accumulated value.\r\n* reverse\r\n    Returns a new reversed seq wrapped.\r\n* sort\r\n    Returns a new sorted seq wrapped.\r\n* toset\r\n    Returns a new set wrapped.\r\n\r\nset specific API\r\n^^^^^^^^^^^^^^^^\r\n* min\r\n    Returns a minimum value.\r\n* max\r\n    Returns a maximum value.",
