Remove Duplicates from Sorted Array

class Solution:
    def removeDuplicates(self, nums: List[int]) -> int:
        a = 0
        for i in range(len(nums)):
            if nums.count(nums[a])>1:
                del nums[a]
            else:
                a+=1

So i solved this leetcode problem which can be found here.

My thought process was simple. I initialized a counter variable (called 'a') that would index the entire array (starting from zero) then i looped through the array while counting each variable. I then check if the count of the variable is greater than 1. If yes, then i delete that particular variable and if no, then i increment the counter variable to move to the next index.
At the end of the day, what is left are numbers whose count are equal to 1.
