How to clear variable in python

Solution:

To clear variable in python you can use del function -

just write-

del variable     

for multiple variable -

del variable1, variable2, variable3

Note: The del statement removes the variable from the namespace, but it does not clear it from memory. We can use  gc.collect()  method after del function to clear the variable from memory.

import numpy as np
import gc

a = np.array([1,2,3])
del a
gc.collect()

or-

You can clear variables by using %reset-f function.

%reset-f

-f does the force action on the given command without prompting for yes/no.

You can also use only

%reset
