How to remove one specific element from a list [duplicate]

Question

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!

Do you want to remove max key from every element? deleting last dict max just works fine using del L1[-1]['max'] — Rahul

@viktor.w it's unclear whether you want to remove the max key from the last dict, or the last dict entirely, or something else. If the first, you've had answers. If the second, you can use lst.pop() or del lst[-1] to remove the last element. If otherwise, you'll need to clarify. — Masklinn

-1 to get the last element of the dict:

del dict_[-1]['max']
print(dict_)

OUTPUT:

[
 {'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, 
  'min': 0.0011927892918825562}
]
