[New-bugs-announce] [issue43580] A Question about List Slice

[LittleGuy]

New submission from LittleGuy <674980165 at qq.com>:

# There is a question when I use list.
# If I run this following code:

x = list(range(10))
a = x[1 : -1 : -1]
print(a)

# the answer will be:
[]

# the right answer should be: [1, 0]
# But in some cases, it works well, like:

a = x[4 : 2 : -1]
print(a)

# the answer will be:
[4, 3]

# so, there may be some problems.
