[New-bugs-announce] [issue17939] Misleading information about slice assignment in docs

[Stefan Chrobot]

New submission from Stefan Chrobot:

http://docs.python.org/3/reference/simple_stmts.html#assignment-statements

The docs says:

"If the target is a slicing: The primary expression in the reference is evaluated. It should yield a mutable sequence object (such as a list). The assigned object should be a sequence object of the same type."

This seems wrong, because the assigned object can be any iterable:

a = [4, 5, 6]
a[0:0] = range(1, 4)
# a is now [1, 2, 3, 4, 5, 6]
