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
