New submission from meng_xiaohui <[email protected]>:
There is a bug in this method：
L.sort(key=None, reverse=False) -> None
L is an instance of list.
Argument key is a function. If L is in the body of argument key, L is always an
empty list in test case, which is wrong
=================
Run this:
F = ['2', '3', '1']
G = ['7', '9', '8']
def key(i):
print(F)
print(G)
res = int(i) + len(F) + len(G)
return res
G.sort(key=key)
F.sort(key=key)
=================
Actual output:
['2', '3', '1']
[]
['2', '3', '1']
[]
['2', '3', '1']
[]
[]
['7', '8', '9']
[]
['7', '8', '9']
[]
['7', '8', '9']
