Clear variable in python

Question

Is there a way to clear the value of a variable in python?

For example if I was implementing a binary tree:

Class Node:
    self.left = somenode1
            


        

Answer 1

• If want to totally delete it use del:

  del your_variable

• Or otherwise, to Make the value None:

  your_variable = None

• If it's an iterable (such as a list or tuple), you can make it empty like:

  your_variable.clear()

Then your_variable will be empty
