Problem 1: Generating a Number with B Repetitions of Digit A Score: 15 Read two positive integers A (1 ≤ A ≤ 9) and B (1 ≤ B ≤ 10). Generate the integer consisting of B repetitions of the digit A. Input Format: A single line containing A and B separatde by a comma and optional spaces. Output Format:...
Problem 1: Narcissistic Numbers (Armstrong Numbers) A Narcissistic number (also known as an Armstrong number or PPDI) is a 3-digit number where the sum of the cubes of its digits equals the number itself. For example: $1^3 + 5^3 + 3^3 = 153$. for candidate in range(100, 1000): hundreds = candidate /...
Command-Line Redirection Operators Standard shell syntax provides the quickest method for capturing script output during execution. The single greater-than symbol (>) overwrites any existing target document, while the double symbol (>>) appends new data without altering previous entries. #...
Prime Number Detection in a Range start = int(input("Enter the lower bound: ")) end = int(input("Enter the upper bound: ")) for candidate in range(start + 1, end): if candidate < 2: continue is_prime = True for divisor in range(2, int(candidate ** 0.5) + 1): if candidate % div...
Creating Directories In Python, you can use the os module's mkdir or makedirs functions to create directories. The mkdir function can only create a single-level directory, while makedirs can recursively create multi-level directories. Using mkdir to Create a Directory import os directory_path = 'ex...

Variable-Length Function Parameters Python supports flexible argument passing using special syntax: def process_data(*params, **config): print(params) print(list(config.items())) process_data(1, 2, name="Zhang", country="China") Output: (1, 2) [('name', 'Zhang'), ('country', 'Chi...
Defining Classes and Instances A class acts as a blueprint for creating specific objects. Variables defined directly within the class body are referred to as member variables. class UserProfile: username = None role = None active_status = None Instantiating the class generates an independent object:...
Constants and Elementary Functions in math The math module ships with Python's standard library and exposes fundamental mathematical constants alongside a broad set of floating-point operations. Access constants like π and e directly: from math import pi, e circle_radius = 5 area = pi * (circle_radi...
Logging Fundamentals Logging provides a mechanism to track software runtime events. Developers instrument their code with logging calls to capture system activities. Each event consists of a descriptive message that may include variable data and is assigned a severity level. Log Severity Levels Leve...
