code: def split_floats(op, min_num, value):
      
      floats = [float(seq) for seq in re.findall(r'(-?\d*\.?\d*(?:e[+-]\d+)?)', value) if seq]
      res = []
      for i in range(0, len(floats), min_num):
          if i > 0 and op in {'m', 'M'}:
              op = 'l' if op == 'm' else 'L'
          res.extend([op, floats[i:i + min_num]])
      return res
docs: Split `value`, a list of numbers as a string, to a list of float numbers.
  
      Also optionally insert a `l` or `L` operation depending on the operation
      and the length of values.
      Example: with op='m' and value='10,20 30,40,' the returned value will be
               ['m', [10.0, 20.0], 'l', [30.0, 40.0]]
