TIL: f-strings Support `=` for Instant Debug Output in Python 3.8+

When debugging Python code, it's often helpful to print out variable names along with their values. In Python 3.8 and later, f-strings provide a convenient way to do this using the = symbol.

Before Python 3.8, you might have written debug print statements like this:

x = 5
y = "hello"
print(f"x: {x}, y: {y}")

But with the new f-string feature, you can simplify this to:

x = 5
y = "hello"
print(f"{x=}, {y=}")

This will output:

x=5, y=hello

As you can see, the = symbol in the f-string causes Python to print both the name and value of each variable.

This feature can be a huge time-saver when debugging complex code, and it's a great example of how Python's syntax continues to evolve and improve.
The ability to use f-strings with = for instant debug output is a game-changer for Python developers, making it easier to quickly identify and fix issues in their code.
