Sociable Dudeney numbers and amicable Dudeney numbers are the powers of their respective roots. The number of iterations i {\displaystyle i} needed for F p , b i ( n ) {\displaystyle F_{p,b}^{i}(n)} to reach a fixed point is the Dudeney function's persistence of n {\displaystyle n} , and undefined if it never reaches a fixed point.
NumPy (pronounced / ˈ n ʌ m p aɪ / NUM-py) is a library for the Python programming language, adding support for large, multi-dimensional arrays and matrices, along with a large collection of high-level mathematical functions to operate on these arrays. [3]
Since 7 October 2024, Python 3.13 is the latest stable release, and it and, for few more months, 3.12 are the only releases with active support including for bug fixes (as opposed to just for security) and Python 3.9, [55] is the oldest supported version of Python (albeit in the 'security support' phase), due to Python 3.8 reaching end-of-life.
The use of unnamed magic numbers in code obscures the developers' intent in choosing that number, [2] increases opportunities for subtle errors (e.g. is every digit correct in 3.14159265358979323846 and can be rounded to 3.14159? [clarification needed] [3]) and makes it more difficult for the program to be adapted and extended in the future. [4]

In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement.
A simple test in Python to check if a number is happy: def pdi_function ( number , base : int = 10 ): """Perfect digital invariant function.""" total = 0 while number > 0 : total += pow ( number % base , 2 ) number = number // base return total def is_happy ( number : int ) -> bool : """Determine if the specified number is a happy number ...
