My variable L1 looks this:
[{'distance': 1.9999,
  'breakEvenDistance': 1.9329,
  'max': 0.0010342833053929787},
 {'distance': 1.9251,
  'breakEvenDistance': 2.0669999999999997,
  'max': 0.0011183923895419084,
  'min': 0.0010342833053929787},
 {'distance': 1.8802,
  'breakEvenDistance': 1.6758,
  'max': 0.0011927892918825562,
  'min': 0.0011183923895419084},
 {'distance': 1.8802,
  'breakEvenDistance': 1.5956,
  'max': 0.0012522046577102665,
  'min': 0.0011927892918825562}]
What I need is to remove the last 'max' in my list! I tried to check the doc, used the function del on L1[-1]['max'] but did not work.. any idea or clue? thanks!
