using python:  how to make sure a string ends with a certain word. for example: I want to raise an AssertionError if an email given as input does not end in "@gmail.com". CANNOT use .endswith( )

Assign to maxSum the max of (numA, numB) PLUS the max of (numY, numZ). Use just one statement. Hint: Call findMax() twice in an expression. - I dont understand what I am doing wrong here, I keep getting an error code saying that non-static findMax(numA, numB) cannot be referenced from a static context. Anything helps!    import java.util.Scanner; public class SumOfMax {public double findMax(double num1, double num2) {double maxVal; // Note: if-else statements need not be understood to// complete this activityif (num1 > num2) { // if num1 is greater than num2,maxVal = num1; // then num1 is the maxVal.}else { // Otherwise,maxVal = num2; // num2 is the maxVal.}return maxVal;} public static void main(String [] args) {double numA = 5.0;double numB = 10.0;double numY = 3.0;double numZ = 7.0;double maxSum = 0.0; // Use object maxFinder to call the methodSumOfMax maxFinder = new SumOfMax(); maxSum= (findMax(numA,numB)+findMax(numY,numZ));     System.out.print("maxSum is: " + maxSum);}}

import java.util.Scanner; public class CircleAndSphereWhileLoop{    public static final double MAX_RADIUS = 500.0;        public static void main(String[] args)    {        Scanner in = new Scanner(System.in);         // Step 2: Read a double value as radius using prompt         //         "Enter the radius (between 0.0 and 500.0, exclusive): "         // Step 3: While the input radius is not in the ragne (0.0, 500.0)        //            Display a message on one line (ssuming input value -1)        //               "The input number -1.00 is out of range."        //            Read a double value as radius using the same promt                 double circumference = 2 * Math.PI * radius;        double area = Math.PI * radius * radius;        double surfaceArea = 4 * Math.PI * Math.pow(radius, 2);        double volume = (4 / 3.0) * Math.PI * Math.pow(radius, 3);                // Step 4: Display the radius, circle circumference, circle area,        //         sphere surface area, and…

Define the method printValue() that takes two integer parameters and outputs the product of all integers starting with the first and ending with the second parameter, followed by a newline. The method does not return any value. Ex: If the input is 3 7, then the output is: 2520 Note: Assume the first integer parameter is less than the second. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16     import java.util.Scanner;   public class ValuePrinter {   /* Your code goes here */   publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intnumber1; intnumber2;   number1=scnr.nextInt(); number2=scnr.nextInt(); printValue(number1, number2); } }
