<｜begin▁of▁sentence｜>### Instruction:
As a networkX researcher, I understand the importance of precision and accuracy in defining the parameters of a rectangular shape for data visualization. Suppose you are working on a network graph visualization project and have received data indicating the Y coordinate of the bottom edge of a rectangle and its height. In this scenario, you may need to calculate and set the Y coordinate of the top edge of the rectangle using the Matplotlib API to ensure that the visualization accurately represents the network structure.
### Response:
from matplotlib.patches import Rectangle

# Create a matplotlib rectangle
rect = Rectangle((0.1, 0.2), 0.5, 0.3)

# Set the Y coordinate of the top edge of the rectangle
rect.set_y(0.4)

# The top edge Y coordinate
rect_top = rect.get_y() + rect.get_height()
print(f'The top Y coordinate of the rectangle is {rect_top}')
