如何为字典中的单个键添加多个值 - python

Question

i have a dictionary : table name :

     {
        column 1:
            {
            value 1 : [data,data,data]
            }
        column 2:
            {
            value 1 : [data,data,data]
            }
     }

now i want to add value 2 inside each column and those values are stored inside a list

list1 = [{value2 : [data,data]}, {value2 : [data,data]}

table name :

     {
        column 1:
            {
               value 1 : [data,data,data]
               value 2 : [data,data]
            }
        column 2:
            {
               value 1 : [data,data,data]
               value 2 : [data,data]
            }
      }

Answer 1

Its not clear , I hope you are asking adding key and list of value into dictionary inside a dictionary

You can do that like this:

tablename[column 1][newKey] = [list of values]

example

tablename= {

    'col1' : {
        'val1':[1,2,44,5],
        },
    'col2' : {
        'val1' : [2,3,47,70]
    }

}

Output will be

{'col1': {'val1': [1, 2, 44, 5]}, 'col2': {'val1': [2, 3, 47, 70]}}

Adding new key:

tablename['col1']['val2'] = [1,2]
tablename['col2']['val2'] = [3,4]

This output will be

{'col1': {'val1': [1, 2, 44, 5], 'val2': [1, 2]}, 'col2': {'val1': [2, 3, 47, 70], 'val2': [3, 4]}}

I hope this will helps.

Answer 2

You can try this as well

tablename= {

    'col1' : {
        'val1':[1,2,44,5],
        },
    'col2' : {
        'val1' : [2,3,47,70]
    }

}

then add new key like this

val2 = [1,2,3,4]
tablename['col1']['val2'] = val2 
tablename['col2']['val2'] = val2
