TypeError: 'Patch' object is not subscriptable

TypeError: ‘Patch’ object is not subscriptable

$ python -c "import matplotlib.pyplot as plt; p = plt.Rectangle((0,0),1,1); p[0]"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
TypeError: 'Patch' object is not subscriptable

Why this happens

Patch artists are objects, not sequences.

Fix

Access attributes (e.g., get_x(), get_y()) instead of indexing.

Wrong code

import matplotlib.pyplot as plt
p = plt.Rectangle((0,0), 1, 1)
x = p[0]

Fixed code

import matplotlib.pyplot as plt
p = plt.Rectangle((0,0), 1, 1)
x = p.get_x()
