This article provides an in-depth analysis of the common TypeError encountered when using Matplotlib's plt.subplots() function: 'AxesSubplot' object is not subscriptable. It explains how the return structure of plt.subplots() varies based on the number of subplots created and the behavior of the squeeze parameter. When only a single subplot is created, the function returns an AxesSubplot object directly rather than an array, making subscript access invalid. Multiple solutions are presented, including adjusting subplot counts, explicitly setting squeeze=False, and providing complete code examples with best practices to help developers avoid this frequent error.
