TypeError got multiple values for argument

Question

I read the other threads that had to do with this error and it seems that my problem has an interesting distinct difference than all the posts I read so far  namely  all the other posts so far have the error in regards to either a user created class or a builtin system resource  I am experiencing this problem when calling a function  I can t figure out what it could be for  Any ideas   BOX LENGTH   100 turtle speed 0  fill   0 for i in range 8       fill    1     if fill   2    0          Horizontol drawbox BOX LENGTH  fillBox   False      else          Horizontol drawbox BOX LENGTH  fillBox   True       for i in range 8           fill    1         if fill   2    0              Vertical drawbox BOX LENGTH fillBox   False          else              Vertical drawbox BOX LENGTH fillBox   True    Error message       Horizontol drawbox BOX LENGTH  fillBox   True  TypeError  Horizontol drawbox   got multiple values for argument  fillBox

This happens when a keyword argument is specified that overwrites a positional argument. For example, let's imagine a function that draws a colored box. The function selects the color to be used and delegates the drawing of the box to another function, relaying all extra arguments.

def color_box(color, *args, **kwargs):
    painter.select_color(color)
    painter.draw_box(*args, **kwargs)

Then the call

color_box("blellow", color="green", height=20, width=30)

will fail because two values are assigned to color: "blellow" as positional and "green" as keyword. (painter.draw_box is supposed to accept the height and width arguments).

This is easy to see in the example, but of course if one mixes up the arguments at call, it may not be easy to debug:

# misplaced height and width
color_box(20, 30, color="green")

Here, color is assigned 20, then args=[30] and color is again assigned "green".

This also happens if you forget selfdeclaration inside class methods   Example   class Example        def is overlapping x1  x2  y1  y2             Thanks to https   stackoverflow com a 12888920 940592         return max x1  y1   lt   min x2  y2    Fails calling it like self is overlapping x1 2  x2 4  y1 3  y2 5   with       TypeError  is overlapping   got multiple values for argument  x1    WORKS   class Example        def is overlapping self  x1  x2  y1  y2             Thanks to https   stackoverflow com a 12888920 940592         return max x1  y1   lt   min x2  y2

I had the same problem that is really easy to make  but took me a while to see through   I had copied the declaration to where I was using it and had left the  self  argument there  but it took me ages to realise that   I had  self myFunction self  a  b  c  123     but it should have been   self myFunction a  b  c  123

I was brought here for a reason not explicitly mentioned in the answers so far  so to save others the trouble   The error also occurs if the function arguments have changed order - for the same reason as in the accepted answer  the positional arguments clash with the keyword arguments   In my case it was because the argument order of the Pandas set axis function changed between 0 20 and 0 22   0 20  DataFrame set axis axis  labels  0 22  DataFrame set axis labels  axis 0  inplace None    Using the commonly found examples for set axis results in this confusing error  since when you call   df set axis   a    b    c    axis 1    prior to 0 22    a    b    c   is assigned to axis because it s the first argument  and then the positional argument provides  multiple values

My issue was similar to Q---ten s  but in my case it was that I had forgotten to provide the self argument to a class function   class A      def fn a  b  c True           pass   Should become  class A      def fn self  a  b  c True           pass   This faulty implementation is hard to see when calling the class method as   a obj   A   a fn a val  b val  c False    Which will yield a TypeError  got multiple values for argument  Hopefully  the rest of the answers here are clear enough for anyone to be able to quickly understand and fix the error  If not  hope this answer helps you

Simply put you can t do the following   class C object       def x self  y    kwargs             Which y to use  kwargs or declaration           pass  c   C   y    Arbitrary value  kwargs  y      Arbitrary value  c x y    kwargs    FAILS   Because you pass the variable  y  into the function twice  once as kwargs and once as function declaration

This exception also will be raised whenever a function has been called with the combination of keyword arguments and args  kwargs Example  def function a  b  c   args    kwargs       print f quot a   a   b   b   c   c   args   args   kwargs   kwargs  quot    function a 1  b 2  c 3    4     And it ll raise  TypeError                                 Traceback  most recent call last   lt ipython-input-4-1dcb84605fe5 gt  in  lt module gt  ---- gt  1 function a 1  b 2  c 3    4     TypeError  function   got multiple values for argument  a    And Also it ll become more complicated  whenever you misuse it in the inheritance  so be careful we this stuff   1- Calling a function with keyword arguments and args  class A      def   init   self  a  b   args    kwargs           self a   a         self b   b      class B A       def   init   self   args    kwargs            a   1         b   2         super B  self    init   a a  b b   args    kwargs   B 3  c 2   Exception  TypeError                                 Traceback  most recent call last   lt ipython-input-5-17e0c66a5a95 gt  in  lt module gt       11         super B  self    init   a a  b b   args    kwargs       12  --- gt  13 B 3  c 2    lt ipython-input-5-17e0c66a5a95 gt  in   init   self   args    kwargs        9         a   1      10         b   2 --- gt  11         super B  self    init   a a  b b   args    kwargs       12       13 B 3  c 2   TypeError    init     got multiple values for argument  a   2- Calling a function with keyword arguments and kwargs which it contains keyword arguments too  class A      def   init   self  a  b   args    kwargs           self a   a         self b   b      class B A       def   init   self   args    kwargs            a   1         b   2         super B  self    init   a a  b b   args    kwargs   B     a   2    Exception  --------------------------------------------------------------------------- TypeError                                 Traceback  most recent call last   lt ipython-input-7-c465f5581810 gt  in  lt module gt       11         super B  self    init   a a  b b   args    kwargs       12  --- gt  13 B     a   2     lt ipython-input-7-c465f5581810 gt  in   init   self   args    kwargs        9         a   1      10         b   2 --- gt  11         super B  self    init   a a  b b   args    kwargs       12       13 B     a   2    TypeError    init     got multiple values for keyword argument  a
