As No import any library To Do This

```
x=[['A',1],['B',2],['C',3]]
y=[['A',100],['B',200],['C',300]]
z=[['A',1000],['B',2000],['C',3000]]

output must:
{'A':[1,100,1000],'B':[2,200,2000],'C':[3,300,3000]}

```

I tried :

```
dic=dict(filter(lambda i:i[0]==i[0],[x,y,z]))

```

So As Data I need first duplicated value to key , and common values to this key as list
