What does the “at” (@) symbol do in Python? - Stack Overflow
Functions, in Python, are first class objects - which means you can pass a function as an argument to another function, and return functions. Decorators do both of these things. If we stack decorators, the function, as defined, gets passed first to the decorator immediately above it, then the next, and so on.

Why doesn't Python have a sign function? - Stack Overflow

Sign function in Python (sign/signum/sgn, copysign)
In Python, the built-in functions and standard libraries do not provide the sign function, i.e., the function that returns 1, -1, or 0 depending on the sign of a number. If you need such a function, you could use numpy.sign() from NumPy or define your own function.
