How to get original values + encoded values mapping ?

[VinayChaudhari1996]

Problem (dataframe having)
index weekday
0 Sunday
1 Sunday
2 Wednesday
3 Monday
4 Monday
5 Thursday
6 Tuesday

---

After encoding :-

index weekday
0 3
1 3
2 6
3 1
4 1
5 4
6 5

Now how do I get original + encoded values mapping like :-

{'Sunday':3, 'Wednesday':6 ..... }

Thanks ,
