<｜begin▁of▁sentence｜>### Instruction:
Given the dimensions and the initial position of a rectangle, can you change the X coordinate of the left side of the rectangle to a new value using the set_x method, and then print the updated position?
### Response:
from matplotlib.patches import Rectangle

# Create a rectangle instance
rect = Rectangle((0, 0), 10, 10)

# Set the X coordinate of the left side of the box
rect.set_x(5)

# Now the left side of the rectangle should be at X=5
print('Left side X coordinate:', rect.get_x())
