The best way to fix the axessubplot' object is not subscriptable error

Question

I am working with python and getting the error message:

---------------------------------------------------------------------------
 TypeError Traceback (most recent call last)
 <ipython-input-108-ce962754d553> in <module>()
 ----> 2 axs[0, 0].boxplot([df1['x'], df2['x']])
  3 plt.show();
  4 
 
 TypeError: 'AxesSubplot' object is not subscriptable

Here is the detail of the code that I ran

fig, axs = plt.subplots()
 axs[0, 0].boxplot([df1['x'], df2['x']])
 plt.show();

I need an explanation for the problems I've encountered. How to fix axessubplot' object is not subscriptable?

The cause:

fig, axs = plt.subplots()

Above command returns a figure that has only one subplot, but axs holds it with no indexing.

fig, axs = plt.subplots(3)

A 1D array with subplots is returned.

fig, axs = plt.subplots(3, 2)

Returns a 2D array with subplots. This is because the default setting for the kwarg, so the error happens. Solution: You can suppress this problem by setting False in the .subplots() command to force it return the result to be a 2-dimensional array, regardless of how many or arrange the subplots.
