I'm using Sage from the interactive shell. How can I clear/remove all the variables I have defined so far in my current session?
You can use reset():
sage: a = 3
sage: a
3
sage: reset()
sage: a
---------------------------------------------------------------------------
NameError Traceback (most recent call last)
[...]
NameError: name 'a' is not definedYou can also give variable names, like reset("a b c") and so on. Type reset? at the console for the details.
Doing this in Sage 7.6 gives:
sage: a=2; a
2
sage: reset()
sage: a
Traceback (most recent call last):
...
NameError: name 'a' is not defined
sage: quit
Traceback (most recent call last):
...
NameError: name 'quit' is not definedThis issue is considered in this ticket: reset does not restore "quit"
%reset -s looks like a potentially better way to do this.
