for p in ax.patches:
#     # bar
#     ax.annotate(np.round(p.get_height(), decimals=2), 
#                 (p.get_x() + p.get_width() / 2., p.get_height()),
#                 ha='center',
#                 va='center',
#                 xytext=(0, 10),
#                 textcoords='offset points')
    # barh
    ax.annotate(np.round(p.get_width(), decimals=4), 
                (p.get_x() + p.get_width(), p.get_y()), 
#                 ha='center',
#                 va='center',
                xytext=(2, -10), 
                textcoords='offset points')

The above code comment style is not as Pythonic as the below one:

for p in ax.patches:
    # # bar
    # ax.annotate(np.round(p.get_height(), decimals=2), 
                  # (p.get_x() + p.get_width() / 2., p.get_height()),
                  # ha='center',
                  # va='center',
                  # xytext=(0, 10),
                  # textcoords='offset points')
    # barh
    ax.annotate(np.round(p.get_width(), decimals=4), 
                (p.get_x() + p.get_width(), p.get_y()), 
                # ha='center',
                # va='center',
                xytext=(2, -10), 
                textcoords='offset points')

Let it be a single line code comment or a block code comment, when we use the shortcut (e.g. Ctrl + / on windows), the # should be indented the same amount as the code line, not be placed at the start of the line.
