    Thread: Understanding how reassignment works
Post: RE: Understanding how reassignment works

Instead of list4[i] = lut[list4[i]]you could do for idx, value in enumerate(lut[list4[i]): list4[i][idx] = valuebut that would be very inefficient. Reassigning is imho the better way to do it.

Post: RE: Understanding how reassignment works

The variables labels01112 and labels11112 are pointers to numpy arrays in memory. With list4 = [labels01112, labels11112]you create a list with two pointers pointing to the numpy arrays. With list4[i]...

Post: RE: Having a hard time combining two parts of code...

If message needs to be a string then the () brackets are the problem. Hopefully you use a python version >= 3.6 then i would suggest using f-string message = f'price: {data["USD"]["last"]}'

    Thread: How to automatically align an image
Post: RE: How to automatically align an image

The easiest and best way doesn't always match, so I'd replace the "and" with an "or". I don't know either, but I would try a convolutional neural net. (Machine learning / AI)

You return three values and assign these to one variable, so that´s a tuple. Nothing you really want. Python has an interesting function named dir() to inspect variables Using this one can see that t...

Post: RE: item = index position - list of list

No, there is no list in a list. Just do a print(program). And in this case pointer is an integer variable, which is used as the index into the list. Of course you need to create a loop. In the loop yo...
