Fwd: keying by identity in dict and set

Hi Dieter, I'm sure that 99% of all use of 'dict' in Python is exactly this. The vast majority of my own Python code is such, and that is as it should be. Here I have an application where I can do something really cool and useful, by keying on identity. The built-in Python structures are pretty

syntax for ellipsis like as "net.blobs['data'].data[...] = transformed_image"

Hi buddies Have a good weekend! I have read some code in caffe, but I confused at "net.blobs['data'].data[...] = transformed_image". The code can be find in this link:https://github.com/BVLC/caffe/blob/master/examples/00-classification.ipynb import caffe model_def = os.path.join(caffe_root, "mo

Thanks too, I have find the answer from "https://stackoverflow.com/questions/772124/what-does-the-python-ellipsis-object-do"; This came up in another question recently. I'll elaborate on my answer from there: Ellipsis is an object that can appear in slice notation. For example: myList[1:2, ...
