To delete a variable, along with its value, use Remove-Variable or Remove-Item . This cmdlet does not delete the values of variables that are set as constants or owned by the system, even if you use the Force parameter.
Delete a variable You can also delete Python variables using the command del “variable name”. In the below example of Python delete variable, we deleted variable f, and when we proceed to print it, we get error “variable name is not defined” which means you have deleted the variable.
Just like the del method, you can invoke the gc. collect() for clearing the memory of not just variables but for all Python objects. Thus, you can use a combination of del() and gc. collect() to clear the variable from Python memory.
The del statement removes the variable from the namespace, but it does not necessarily clear it from memory. Therefore, after deleting the variable using the del statement, we can use the gc. collect() method to clear the variable from memory.
%reset seems to clear defined variables.
EDITED after @ErdemKAYA comment.
To erase a variable, use the magic command:
%reset_selective <regular_expression>
The variables that are erased from the namespace are the one matching the given <regular_expression>.
Therefore
%reset_selective -f a
will erase all the variables containing an a.
Instead, to erase only a and not aa:
In: a, aa = 1, 2
In: %reset_selective -f "^a$"
In: a # raise NameError
In: aa # returns 2
see as well %reset_selective? for more examples and https://regexone.com/ for a regex tutorial.
To erase all the variables in the namespace see:
%reset?
In iPython you can remove a single variable like this:
del x
I tried
%reset -f
and cleared all the variables and contents without prompt. -f does the force action on the given command without prompting for yes/no.
