python - 从列表字典中删除记录

Question

我想从列表字典中删除记录：

data{'key1':[value1,value2,value3,value4]
     'key2':[value1,value2,value3,value4]
     'key3':[value1,value2,value3,value4]}

如何删除所有键中的所有 value2？

Answer 1

data = {
           'key1':['value1','value2','value3','value4'],
           'key2':['value1','value2','value3','value4'],
           'key3':['value1','value2','value3','value4']
        }

for v in data.values():
  if 'value2' in v:
    v.remove('value2')
print(data)
