Hi~~~

def Reclass(arg):
    if arg in ["222", "333"]:
        return "<Null>"
    else:
        return arg

I want the results as shown below.

Nearly there, but you need to pass in 2 arguments.

#prelogic codeblock

def Reclass(arg1, arg2):
    if arg1 in ["222", "333"]:
        return "<Null>"
    else:
        return arg2


#code

Reclass(!NAME!, !PNAME!)‍‍‍‍‍‍‍‍‍‍‍‍

Do not return "<NULL>" because it will not set a field to SQL NULL, it will set a field to a text string that says "<NULL>". If you want to set a field to SQL NULL, you want to return None.
