The Walrus Operator := (Assignment Expressions)

Introduced in Python 3.8, the "walrus operator" := allows you to assign a value to a variable as part of a larger expression. It's a powerful tool for writing more concise and readable code, especially in while loops and comprehensions.

It solves the common problem where you need to compute a value, check it, and then use it again.

---

#### The Old Way: Repetitive Code

Consider a loop that repeatedly prompts a user for input and stops when the user enters "quit".

# We have to get the input once before the loop,
# and then again inside the loop.
command = input("Enter command: ")

while command != "quit":
    print(f"Executing: {command}")
    command = input("Enter command: ")

print("Exiting program.")

Notice how input("Enter command: ") is written twice.

---

#### The Pythonic Way: Using the Walrus Operator :=

The walrus operator lets you capture the value and test it in a single, elegant line.

while (command := input("Enter command: ")) != "quit":
    print(f"Executing: {command}")

print("Exiting program.")

Here, (command := input(...)) does two things:
• Calls input() and assigns its value to the command variable.
• The entire expression evaluates to that same value, which is then compared to "quit".

This eliminates redundant code, making your logic cleaner and more direct.
