Sometimes, we want to create a two way/reverse map with Python.
In this article, we’ll look at how to create a two way/reverse map with Python.
How to create a two way/reverse map with Python?
To create a two way/reverse map with Python, we put the forward and reverse maps in the same dictionary.
For instance, we write
relation = {}
relation['Alice'] = 'Bob'
relation['Bob'] = 'Alice'
to create the relation dict.
Then we add both the mapping from 'Alice' to 'Bob' and vice versa in the same dictionary.
Conclusion
To create a two way/reverse map with Python, we put the forward and reverse maps in the same dictionary.
