python - Can functools.partial be used to bind arbitrary positional arguments? -

Suppose you define partial to set positional arguments in an arbitrary order To correct 2 and 3 th arguments you want, the results you want to apply partial to str.split are as follows:

  Lambda: str.rsplit (S, SEP, 1) #Sep was given.   
 (I use  s.rsplit (...  instead of  str.rsplit (s ...  and To make more points)  
  partial (str.rsplit, sep = SEP, maxsplit = 1) #         SEP   
 but  str.rsplit  does not use keyword logic, only positional.  
 Partially, how to fix those arguments? The only option is long and wrapper?  
 If you want to define the function inline, then the rapper is ugly, like the function's Defining the argument for the dispute.  Lambda  is  Defacto  here, and  partial  is the second option, but in this case it is lacking. You can not do this with the  partial . This is because  The PyArg_ParseTuple  function uses the API that does not provide keyword logic from split . From Python's perspective, it seems that the method is defined as Interpretation:  
  DEF division (self, * Arges): If Len (Arjis) & gt; 2: Increase the type arrow (...) sep = args [0] if the args and none maxsplit = args [1] if LAN (Args)> gt; 1 and -1 ...   
 Can only provide positional logic in partial order. It is mentioned, where they say that  partial  "is almost equivalent":  
  def partial (func, * args, ** keywords): def newfunc (* Fargs, ** fkeywords): newkeywords = keywords.copy () newkeywords.update (fkeywords) return func (* (args + fargs), ** newkeywords) newfunc.func = func newfunc.args = args newfunc.keywords = keyword newfunc   
 Note  return func (* (args + fargs), ** newkeywords)  which clearly shows that you  partial  Other functions are included in Arguments.  
 The conclusion is that  lambda  is more powerful than  partial .  
 On the one hand, in Python 3.3, you can specify  maxsplit  as a keyword argument:  
  & gt; & Gt; & Gt; '' Some strings with spaces ''. (Same as 'max', 'some', 'string', 'empty space']   
 and this was also the same issue for many other methods / functions.
