Sliding Window Median

My Solution:

def medianSlidingWindow(nums: List[int], k: int) -> List[float]:
    sublist = []
    midpoint = 0
    medians = []
    
    for i in range(0, len(nums)-k+1):
        sublist = sorted(nums[i : i+k])
            
        midpoint = math.floor(len(sublist) / 2)
        
        medians.append(sublist[midpoint] if len(sublist) % 2 else (sublist[midpoint] + sublist[midpoint-1]) / 2)
        
        
    return medians
