This is more of a doubt than a new idea. Python has always worked intuitively but this was a bummer.

A list has an append method. So I can do list.append(value).
I tried doing list(range(10)).append(10) and it returns None. I'd usually assume list(range(10)) returns a list, to which I can append whatever I want.
I tried this with List comprehension also. Doesn't work there either.
Why doesn't this work?
Moreover, shouldn't it work?
How do I add that feature in Python?
