List/bytearray fill with single value/object

[srepmub (Mark Dufour)]

Thanks, I fully agree! Btw, I apologise for starting a new thread for this. I just came across this one:

Idea: Allow assigning a scalar to all elements of a list slice, just as is allowed with a numpy array

It is easy to assign the same scalar value to every element of a slice of a numpy array, but not so easy for a python list: somenparray[start::step]=42 Doing that to a slice of python list requires specifying how many elements are in the slice: somelist[start::step]=lenslice*[42] # You have to figure out lenslice and create a list of that length. Further example: import numpy as np def lenpositiverange(start,limit,step): # how many items in the slice or range for posiive steps retu…

What would be a next step for this, probably a PEP would be required..?
