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.

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"?

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've been doing some searching but I couldn't find any consensus on the syntax allowed for imports.
I threw an syntax error for this import and was wondering if there was documentation on allowable syntax.
import some-module
# Do stuff.
You can't use hyphen('-') symbol in any names in Python as this is regarded as substraction operator. Use underscore ('_') instead.

f-strings giving SyntaxError?
(7 answers)
Closed 5 years ago.
I have a variable called method, it's value is POST but when I try to run print(f"{method} method is used.") it keeps giving a syntax error at the last double quote and I can't find the reason on why it does this. I am using python 3.5.2.
F-strings were a new feature introduced in Python 3.6, so of course they're not going to work in 3.5.2.

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.
I bealive, this is taken origin from Usage message
