I have two functions in a class, plot() and show(). show(), as convenience method, does nothing else than to add two lines to the code of plot() like

def plot(self,show_this=True,show_that=True,color='k',boundary_color=None,other_color=[0.8, 0.8, 0.8],show_axes=True):# lots of codereturndef show(self,show_this=True,show_that=True,color='k',boundary_color=None,other_color=[0.8, 0.8, 0.8],show_axes=True):from matplotlib import pyplot as pltself.plot(show_this=show_this,show_that=show_that,color=color,boundary_color=boundary_color,other_color=other_color,show_axes=show_axes)plt.show()return

This all works.

The issue I have is that this seems way too much code in the show() wrapper. What I really want: Let show() have the same signature and default arguments as plot(), and forward all arguments to it.

Any hints?

Python 3 offers the ability to actually copy the signature of the wrapped function with the inspect module:

def show(self, *args, **kwargs):from matplotlib import pyplot as pltself.plot(*args, **kwargs)plt.show()
show.__signature__ = inspect.signature(plot)

Now if you use show in a shell that provides autocompletion like IDLE, you will see the correct parameters for show instead of the cryptics *args, **kwargs
