I have never seen this repeated dot syntax, and I can't find any pointers to it anywhere.
Is it application of unsqueeze followed by expand followed by float() ?
input_mask_expanded = (attention_mask
.unsqueeze(-1)
.expand(token_embeddings.size())
.float())
It's equivalent to
input_mask_expanded = (attention_mask.unsqueeze(-1).expand(token_embeddings.size()).float())
Just in a more readable form

I'm using python 3.10.4 right now.
I mistakenly wrote ["somestring" "somestring"] without a , separating the strings. Which evaluated to ["somestringsomestring"] without raising an error (which an error raised was my expectation).
And it seems like it was like that for previous versions.
How should I interpret the process of "string" "string" being evaluated to "stringstring"?

Lots of old python code I look in has this ` symbol around a lot of stuff, what does it do? Now it is not considered valid syntax, obviously.
And I don't think it is just another string identifier, its sometimes wrapped around functions in the code I'm looking at.
Any help will be appreciated.

How to replace multiple substrings of a string?
(28 answers)
Closed 4 years ago.
I currently have the below Python code which works well:-
caseURL = r"\\mydomain\abc\lp_t\GB\123456\Original Format"
caseURL = caseURL.replace("lp_t", "lp_i")
caseURL = caseURL.replace("Original Format", "1")
This works fine as said and carries out the below conversion:-
\\mydomain\abc\lp_t\GB\123456\Original Format
\\mydomain\abc\lp_i\GB\123456\1\
This however just seems a bit clumsy. Is there a more pythonesque way to perform these two segment replacements?
Thanks

I'm using python for a long time. but it was always strange to me why In python references, commands are written like this:
del var1[,var2[,var3[....,varN]]]]
I know that if I want to use the above command I should write it in this way:
del var1, var1
I can't understand the meaning of [] is it related to the lists? any help will be appreciated.
Its just showing that these parameters are optional. This is normal style for references.
There is nothing to do with this in python. Just a tutorial explanation.
