[FIXED] How to remove space after comma in list in python

Issue

class Solution:
    def buildArray(self, nums):
    
        ans=[]
        for i in range(len(nums)):
            ans.append(nums[nums[i]])
        return ans

    
sol = Solution()  
res = sol.buildArray([0,2,1,5,3,4])
print(res)

output:

[0, 1, 2, 4, 5, 3]

The problem is in the output , iam sturggling to remove space after comma ',' in the list . Can any body help me with this one

Solution

You need to turn the list into a string first, which will make that kind of manipulation easier.

Try replacing your last line for this:

res_str = str(res).replace(", ", ',')
print(res_str)
