Understanding How to Check if Variable is Null
Python uses None instead of null, so in this article, I'd like to show with you the best way to check if the variable is null (None)
Checking if a variable is null [Method 1]
syntax:
not variable:example:
#variable
variable_1 = None
if not variable_1:
print("yes! the var is null")
output
yes! the var is null
Checking if a variable is Null [Method 2]
syntax:
is None:example:
#variable
variable_1 = None
if variable_1 is None:
print("yes! the var is null")
output
yes! the var is null
