random integers,removing elements

I have been trying several ways to remove some elements and can't seem to get it to work. The program needs the [] and ,. I have tried nums.remove(x).

  import random
  ROWS = 7
  COLS = 1

  def main():
      nums = [0, 0, 0, 0, 0, 0, 0]
      for r in range(ROWS):
          nums[r] = random.randint(20, 80)
      nums = [int(r) for r in nums]
      print(nums)
      print('The largest integer is',max(nums))
      print('The lowest integer is',min(nums))
      nums.sort()
      print('The middle 5 sorted low to high',nums, )


  main()

desired output:

79 30 39 33 41 43 53 
The highest number is 79
The lowest number is 30
The middle 5 sorted high to low:
43 41 39 33 30

Current output:

[22, 35, 39, 24, 75, 24, 33] 
The largest integer is 75 
The lowest integer is 22 
The middle 5 sorted low to high [22, 24, 24, 33, 35, 39, 75]
