What is the number in dictioinary key names

In the variabls pane, while debugging, a big number appears right next to the names of dictionary keys. What's that?

For eg, a simple dictionary - d = {'a':1} , look like { 'a' (139726674695984) : 1}  in the variables pane.


What is this number 139726674695984?

Those are dict-specific hashes, and they are pretty much useless for most programmers. We have a request to remove them: https://youtrack.jetbrains.com/issue/PY-25163
