Error in listing a Zip

To plot a Lorenz curve I add
A=list(zip(percumsumavbinbilles1,percumsumpop))
as show by If you meant to plot two lists 'x' and 'y' against each other, use 'list_plot(list(zip(x,y)))' in https://doc.sagemath.org/html/en/reference/plotting/sage/plot/plot.html
But this generate an error 'list' object is not callable. Could somebody explain my mistake?
A = list(zip(...))worked for me, returning[(0, 0), (0.00968342644320298, 0.24154589371980675), (0.0633147113594041, 0.6280193236714976), (0.1931364724660814, 0.7294685990338164), (0.4530460228784251, 0.8647342995169082), (1.0, 1.0)].WorksForMe(TM) in 10.0.beta4 (up to a formatting error in your code when pasted in my console : in Python/Sage, blank space is syntactic !)
BTW, this can be done much more easily in R ... which is quite easily callable from Sage.
My version is 9.7. But I encounter the same problem with 9.3. And sorry for the blank space. It was only a typesetting error not present in my original code. But I have tried this simple following code
which works in both versions.Then after this it works for my first exemple. I do not understand. Sorry
Did you perhaps use
listas a variable name? For example if you first didlist = [1,2,3]and then later didlist(zip(A,B)), you would get the error you described.
