Hi everybody,  
I needed to compare a string with NULL or see if the string is empty.  
I tried the python function .isNull() \>\> doesn’t works.  
I tried isNull(string\_to\_compare) \>\> doesn’t works.  
Finally I founded:  
if (string\_to\_compare == None):

else:

Trying to help,

In python, null is `None`, and has no properties or methods of its own. The correct check is `if something is None:`

However, if you want empty to be treated the same, just do `if something:`. In a boolean context, empty strings and `None` both evaluate to `False`.
