Consider the following Python code: def valid_input(user_in):   num = int(user_in)   return num % 10 == 0: def main():   PROMPT = "Enter an integer that is divisible by 10: "   num = input(PROMPT)   while not valid_input(num):      num = input(PROMPT)   print("Done") This code works as expected if the user enters an integer but crashes if they enter anything else, such as a word. Your task is to rewrite the valid_input function so that it uses a try-except block to handle the case where the user enters something that cannot be converted to an integer. Your version of valid_input should return True if user_in is an integer that is divisible by 10 and False in all other cases. The except branch should catch the specific exception that's thrown if the user enters something other than an integer.

JAVA Programming Language: According to the American Heart Association, as you exercise you should periodically check your heart rate to ensure you are in your target zone.  Your target zone is a range that is 50% to 85% of your maximum heart rate.  The formula for calculating a persons maximum heart rate is 220 minus your age in years. Write a program that reads the users current heart rate, birthday, and the current day (each consisting of month, day, and year).  The program should calculate the persons age (in years), the person's maximum heart rate, and the person's target heart rate zone range. Output the users age, current heart rate, target zone range. If their heart rate is in the target zone congratulate them, if it is out of their target zone warn them. Required Methods (Write these first and use them in your algorithm): (your code, particularly for computeAge, must be 100% clear and documented - it's the core of this assignment!) int computeAge(int birthMonth, int birthDay,…

Input and Output in Python Write a complete Python program that asks the user for a positive integer number as n and then writes out all the numbers from 1 up to and including that number n . If user enters a negative integer, a message should display You must enter a positive number!. Your program's output should look like the following: The example below is using -4 and 6 as input Enter a positive number: -4 You must enter a positive number! Enter a positive number: 6 123 456 NumberRange.py 1 n = int(input('1')) # as the input() function returns a string, using the int() function to convert that input to an integer + 2 3 # if number is or negative then print a message 4 if (n <= 0): 5 print('6¹) 6 else: 7 #if mumber is positive, then running a for loop that starts from 1 and ends at number both inclusive 8 # as the __stop argument to the range() function is exclusive, we need to use number + 1 instead so that the number itself is also included in the for loop iteration. for i in…

A complex number is a number in the form a+bi, where a and b are real numbers and i is √(-1)   The numbers a and b are known as the real part and imaginary part of the complex number, respectively. You can perform addition, subtraction, multiplication, and division for complex numbers using the following formulas:   a + bi   +   c + di  =  (a+c) + (b+d)i    (addition) a + bi   −  (c + di) = (a−c) + (b−d)i   (subtraction) (a + bi) * (c + di) = (ac−bd) + (bc+ad)i   (multiplication) (a + bi) / (c + di)  = (ac+bd) / (c2+d2) + (bc−ad)i / (c2+d2)   (division)   You can obtain the Absolute Value for a complex number using the following formula: |a + bi|  =  √(a2 + b2)   A Complex number can be interpreted as a point on a plane by identifying the (a,b) values as the coordinates of the point. The absolute value of the complex number corresponds to the distance of the point to the origin, as shown in the example below.   (1) Design a class named Complex for representing complex numbers Include…
