Does the value remain after the end of the '||' operator block in programming language?

The walrus operator (:=) in Python is an assignment expression operator introduced in version 3.8. The value assigned using the walrus remains accessible after the block in which it was used, if the scope allows.

For example:

if (n := len([1, 2, 3])) > 2:
    print(f"List length: {n}")

print(n)  # The value of n is accessible here as well, will output 3

Thus, the value assigned through the walrus operator is stored in a variable and accessible after the block if the variable is declared in the appropriate scope (e.g., within a function or globally).
