Python program for not None test

Python example for None watchword: Here, we will figure out how to check whether a variable contains a worth or not?

As we have talked about in the past post (Python None watchword), that “None” is a catchphrase which can be utilized to appoint an invalid an incentive to a variable or to check whether a variable contains any worth or not.

Example:

Here, we have 3 factors a, b and c, and is being allowed with “Hello“, b is being relegated with “None” and c is being doled out with 10.

We are trying whether factors have a worth or None, on the off chance that they have values, we are printing their qualities.

# python code for not None test

# variable 1 with value
a = "Hello"

# variable 2 with None
b = None

# variable 3 with value 
c = 10

# performing is not None test 
if a is not None:
    print("value of a: ", a)
else:
    print("\'a\' contains None")

if b is not None:
    print("value of b: ", b)    
else:
    print("\'b\' contains None")

if c is not None:
    print("value of c: ", c)
else:
    print("\'c\' contains None")

Output:

value of a:  Hello
'b' contains None
value of c:  10
