python clear all

To clear all variables and functions from the Python namespace, you can use the `globals()` and `locals()` functions along with the `del` statement. Here's an example:

# Clear all variables
vars_to_clear = list(globals().keys()) + list(locals().keys())
for var in vars_to_clear:
    if var.startswith('__') and var.endswith('__'):  # ignore system variables
        continue
    del globals()[var]

Please note that this approach will only clear variables within the current scope. If you have imported modules or variables defined in other scopes, they will not be cleared using this method.
