dir()

[palmerit]

In a university computational course I teach, I have a unit on image processing and use Pillow. I was going over the demo code I have for my course and discovered that dir() does not work anymore when applied to an image object. Odd. I don't think I've ever encountered an object where I could not use dir() to inspect its elements.

Here's the code:

from PIL import Image

im = Image.open('Jordingray.bmp')
print(type(im))
print(dir(im))

It shows the type as:
<class 'PIL.BmpImagePlugin.BmpImageFile'>

Here's the error:

---

TypeError Traceback (most recent call last)
Cell In[108], line 4
1 from PIL import Image
3 im = Image.open('Jordingray.bmp')
----> 4 print(dir(im))

TypeError: 'str' object is not callable

I can't replicate, either locally or on GitHub Actions.

If you can still replicate, would you be able try print("test") and dir("test"), both of which should work, to check that the mystery doesn't lie in print or dir? I mean that if print or dir were strings for some absurd reason, then that would give the error you're seeing.

>>> from PIL import Image
>>> im = Image.new("RGB", (1, 1))
>>> print = "test"
>>> print(im)
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'str' object is not callable

If that doesn't yield anything, could upload the image?

Sorry. I hadn't seen that my graduate student had overwritten the dir() function in my code. Should have been the first thing I checked.
