how to insert a figure into a new subplot in matplotlib

Question

I have a number of functions that return figures, like

def create_predef_plot():
    f, ax = plt.subplots()
    ax.plot(randn(10))
    return f, ax

how can i insert the plot returned by create_predef_plot into f2

plot1 = create_predef_plot()
f2, (ax21, ax22) = subplots(1,2)

1) this has nothing to do with IPython, it is pure matplotlib

2) the common pattern is to use an ax keyword argument.

def create_predef_plot( ax=None ):
    if not ax
        f, ax = plt.subplots()
    ax.plot(randn(10))
    return ax


f2, (ax21, ax22) = subplots(1,2)
create_predef_plot(ax=ax22)
