None Check

[adamranieri]

Please read the PEP 572 to see if your proposition is valid or not.

Describe the solution using the Walrus Operator
To ensure that a value returned from a function is not none when used in your code.

nicknames = {"Bill":"Billy", "John":"Jim", "Theodore":"Ted"}

nickname = nicknames.get("Amy")
if nickname:
    print("The nickname is {nickname}")
else:
    print("No nick name")

Describe alternatives you've used
use the walrus operator to check in one line and keep the variable

nicknames = {"Bill":"Billy", "John":"Jim", "Theodore":"Ted"}

if nickname :=  nicknames.get("Amy"):
    print("The nickname is {nickname}")
else: 
    print("No nick name")
