Python — For Loop

Question 1 For Loop Basics

Extract and Display ASCII / Unicode Code Points of a String

Write a Python program to iterate over a given string ("python"). For each character in the string, retrieve its ASCII/Unicode numerical code using the ord() function, and print the character alongside its corresponding code point separated by a hyphen (-).

Question 4 For Loop Factors Count

Count Total Factors of an Integer

Write a Python program to accept a positive integer from the user. Using a for loop and the modulus operator (%), iterate through all possible divisors from $1$ up to the number itself. Count how many numbers divide the input evenly and print the total factor count.

Question 5 For Loop Extremes

Find the Largest and Smallest Integers Among 10 User Inputs

Write a Python program to read 10 integers sequentially from the user. Without using lists or built-in functions like max() and min(), determine both the largest and smallest numbers entered using a single for loop and conditional statements.
