Problem Description:
------------------ANSWER
import math as m
try:
    n = float(input())
    if n < 0:
        print("Error: Cannot calculate the square root of a negative number.")
    else:
        sqrt = m.sqrt(n)
        print(f"The square root of {n} is {sqrt:.2f}")
except ValueError:

QUESTION ----------------
Write a Python program that asks the user for their age and prints a message based on the age. Ensure that the program handles cases where the input is not a valid integer.
------------------ANSWER
while True:
    try:
        n=int(input())
        if n>=0:
            print("You are ",n," years old.",sep='')
            break
        else:
            print("Error: Please enter a valid age.")
            break
    except:
        print("Error: Please enter a valid age.")
        break

QUESTION ----------------
Develop a Python program that safely performs division between two numbers provided by the user. Handle exceptions like division by zero and non-numeric inputs.
------------------ANSWER
try:
    num1 = float(input())
    num2 = float(input())
    if num2 == 0:
        print("Error: Cannot divide or modulo by zero.")
    else:
        result = num1 / num2
        print(result)
except ValueError:
    print("Error: Non-numeric input provided.")

QUESTION ----------------
Write a Python program that performs division and modulo operations on two numbers provided by the user. Handle division by zero and non-numeric inputs.
------------------ANSWER
while True:
    try:
        a=int(input())
        b=int(input())
        if b==0:
            print("Error: Cannot divide or modulo by zero.")
            break
        else:
            m=a%b
            if m==0:
                print("Division result: %.1f"%(a/b))
                print("Modulo result: %d"%m)
                break
            else:
                print("Division result: %.16f"%(a/b))
                print("Modulo result: %d"%(a%b))
                break
