Python Creating subplots

Let's assume that we want to create the following subplots using matplotlib. This is how we can initiate the plot.

import matplotlib.pyplot as plt    
    
fig = plt.figure(figsize=(10,7), dpi=200)    
ax = fig.add_subplot(2,1,1)    
ax.annotate("This is 2X1 [2 rows and 1 column] and we want to have this plot is 1st position.", 
            (0.5,0.5), horizontalalignment='center')    
ax = fig.add_subplot(2,2,3)    
ax.annotate("This is 2X2 [2 rows and 2 columns].\nWe want to have this plot at 3rd position.",
            (0.5,0.5), horizontalalignment='center')    
ax = fig.add_subplot(2,2,4)    
ax.annotate("This is 2X2 [2 rows and 2 columns].\nWe want to have this plot at 4th position.",
            (0.5,0.5), horizontalalignment='center')
