Where is the loophole in my code

[landlord1984]

Question is:

Given an array nums, write a function to move all 0's to the end of it while maintaining the relative order of the non-zero elements.

For example, given nums = [0, 1, 0, 3, 12], after calling your function, nums should be [1, 3, 12, 0, 0].

Note:

   You must do this in-place without making a copy of the array.
   Minimize the total number of operations.

My code has passed a simple case, but failed an extreme case which has the fifth last element as 0. I don't know where is the loophole in my code.

Here is my code:

class Solution(object):
    def moveZeroes(self, nums):
        i=0
        Count=0
        ZeroCount=0
        MaxCount=(len(nums)-ZeroCount)
        print("Input Size=",len(nums))
        while Count <MaxCount-ZeroCount:
            Count=Count+1
            if nums[i]==0:
               nums.pop(i)
               nums.append(0)
               ZeroCount=ZeroCount+1
               i=i-1
            i=i+1
        return nums    


print(Solution().moveZeroes([0,1,0,3,12]))
print(Solution().moveZeroes([-959151711,623836953,209446690,-1950418142,1339915067,-733626417,481171539,-2125997010,-1225423476,1462109565,147434687,-1800073781,-1431212205,-450443973,50097298,753533734,-747189404,-2070885638,0,-1484353894,-340296594,-2133744570,619639811,-1626162038,669689561,0,112220218,502447212,-787793179,0,-726846372,-1611013491,204107194,1605165582,-566891128,2082852116,0,532995238,-1502590712,0,2136989777,-2031153343,371398938,-1907397429,342796391,609166045,-2007448660,-1096076344,-323570318,0,-2082980371,2129956379,-243553361,-1549960929,1502383415,0,-1394618779,694799815,78595689,-1439173023,-1416578800,685225786,-333502212,-1181308536,-380569313,772035354,0,-915266376,663709718,1443496021,-777017729,-883300731,-387828385,1907473488,-725483724,-972961871,-1255712537,383120918,1383877998,1722751914,0,-1156050682,1952527902,-560244497,1304305692,1173974542,-1313227247,-201476579,-298899493,-1828496581,-1724396350,1933643204,1531804925,1728655262,-955565449,0,-69843702,-461760848,268336768,1446130876]))

I highlighted the 0 in red that is missed by the expected operation.
