That's not an expression; it is an assignment statement.
The right-hand side is an expression. It will (at the top level) create
a list.
To create a new instance of the 'list' type, Python will call the type's
'__new__' method. This is termed the constructor fo

It doesn't actually have double backslashes in it, that's just a
result of how the string is being displayed. No conversion is
needed.

I get a string item, for example path[0], from path = os.get_exec_path()
It's something like "\\Borland\\Bcc55\\Include", a Python string.
I want to use this "string" in a subprocess command as a parameter.
Obviously this command can only recognize "\Borland\Bcc55\Include".
I know there must have

Python doesn't really go in for that philosophy.
Exceptions are often used for flow control, e.g.
StopIteration.

None. Simple assignment does not call any methods. It just takes the
value on the right hand side and says, hey, "L", you now mean that
thing, k?
Hello gauys,
Which list class method will call for below codes?
L = [1,2,3]
And
L =[]
Thanks,

Could you please try another tool like `convert'? E.g.
$ convert 102_PANA/P1020466.JPG test.png
What does that say?

I have a program which uses jpegtran-cffi 0.5.2 and, while it seems to
work OK most of the time it's hanging very solidly on one jpeg file
which seems to be OK when viewed with other programs.
I'm simply doing:-
img = JPEGImage(srcFullFn)
I have checked that that srcFullFn points to a real j

Do you mean this?

I'm converting an existing Python2 program to Python3, it uses
jpegtran and I can't find what to install to get this in Python3.
Can anyone advise what I need to install in Python3?
