This is very easy to know in python that if any variable is empty or not
try to use :
if not ur_var:
print "variable is empty
get attention towards not keyword . This does all things .
This is equivalent to empty($ur_var) in php
not keyword in python also checks for lists (array) , objects , strings , integrers , floats etc ..
example :
a= 0 or a = "" or a ={} or a= []
if not a :
print "empty"
in all cases it will print empty .
