in python, you may sometimes need to clear all variables from the current namespace, especially when working in interactive environments like jupyter notebooks or ipython shells. clearing variables can help in avoiding conflicts or simply cleaning up the workspace. in this tutorial, we'll explore different methods to achieve this.
one straightforward method to clear all variables is by using the globals() function, which returns a dictionary representing the current global symbol table. we can then remove all entries from this dictionary except for the built-in ones.
this method removes all variables except for those that are built-in, such as __name__, __doc__, etc.
another approach is to use the locals() function, which returns a dictionary representing the current local symbol table. however, this method should be used with caution, especially in functions or methods, as it only clears variables from the local scope.
