Question

In python, if I create a local variable _ (underscore) and assign it to something:

_ = 3

Is it possible to reverse that assignment to regain usage of the underscore as the last returned output in the REPL?

Answer 1

Yes. Use the del statement.

$ python
>>> _ = 3
>>> _
3
>>> 5
5
>>> _
3
>>> del _
>>> 6
6
>>> _
6
