ValueError: 'a' is not in list Here is how you can search a sub list : >>> myList.index(["a", "true"]) 6 If it is desired to just whether an element is present in a list, it can be done in following way : >>> "sun" in myList True So we see that ‘True’ was retur...

It means the number of zero-paddings on both sides for each dimension. If `padding` is a string, either 'VALID' or 'SAME' which is the padding algorithm. If padding size is a tuple or list, it could be in three forms: `[pad_depth, pad_height, pad_width]` or `[pad_depth_front...
