# My python code works on my machine

• on my machine, I can get '01', but OJ gets '10', can anyone help?

``````class Solution:
# @param A a list of integers
# @return nothing, sort in place
def sortColors(self, A):
length = len (A)
p = 0
for i in range(length):
if A[p]==0:
A=[0] + A[:p]+A[p+1:]
p+=1
elif A[p]==2:
A= A[:p]+A[p+1:]+[2]
else:
p+=1
return A

sol = Solution()
print sol.sortColors([1,0])``````

• The problem asks to "sort in place". I guess that means to modify one or two elements in the list A in each step, instead of reconstructing the list A.

After removing the last two lines and modifying another two lines from you codes, the submission is accepted.
The two lines modified are:

1. Replace the line `A=[0] + A[:p]+A[p+1:]`
with `del A[p]` and `A.insert(0,0)` .
1. Replace the line `A= A[:p]+A[p+1:]+[2]` with
`del A[p]` and `A.append(2)` .

• Hi ncchen, thanks a lot!
