Concept explainers

Types of Loop

Loops are the elements of programming in which a part of code is repeated a particular number of times. Loop executes the series of statements many times till the conditional statement becomes false.

Loops

Any task which is repeated more than one time is called a loop. Basically, loops can be divided into three types as while, do-while and for loop. There are so many programming languages like C, C++, JAVA, PYTHON, and many more where looping statements can be used for repetitive execution.

While Loop

Loop is a feature in the programming language. It helps us to execute a set of instructions regularly. The block of code executes until some conditions provided within that Loop are true.

Question

Need python code with using a while loop

Sum of positive numbers
Write a program with a loop that asks the user to enter a series of positive numbers.
The user should enter a negative number t signal the end of the series. After all the
positive numbers have been entered, the program should display the sum of the
numbers.
Hints
• Use a while loop for input validation. The negative number will be the "sentinel"
that will cause the Boolean expression being evaluated to become false
•You will also need an IF statement
Check with the following values:
100
100
-1
Result:
Total = 200

(Mathematical functions) Write a program that calculates and displays values for y when y=xz/(xz) Your program should calculate y for values of x ranging between 1 and 5 and values of z ranging between 2 and 6. The x variable should control the outer loop and be incremented in steps of 1, and z should be incremented in steps of 1. Your program should also display the message Function Undefined when the x and z values are equal.
Sum of NumbersWrite a program that asks the user for a positive integer value. The program should usea loop to get the sum of all the integers from 1 up to the number entered. For example,if the user enters 50, the loop will find the sum of 1, 2, 3, 4, … 50.Input Validation: Do not accept a negative starting number.
Problem 2: Safe Square Root Write a program to take the square root of a number typed in by the user. Your program should use a while-loop to ensure that the number they typed in is positive. If the number is negative, you should print out a warning “The number is negative. Try again.” and re-prompt the user to take a valid input. You can get the square root of a number n with Math.sqrt(n). Make sure you don't do this until the loop is done and you know for sure you've got a positive number. Sample input and output: Enter a number > -9 The number is negative. Try again. Enter a number > 9 The square root of 9 is 3.0 Enter a number > 2 The square root of 2 is 1.4142135623730951

Budget Analysis (Running Total)Write a program BudgetAnalysis.py) that asks the user to enter the amount of money that he or she has available to spend on electronics this year. A loop should then prompt the user to enter each of his or her expenses for electronics and keep a running total. When the loop finishes, the program should display the total amount that the user spent, and analyse if there is still money to buy more electronics. Here are two test runs of the program: Enter your available amount for electronics in 2020: 1500 Enter your expense (-1 for stop): 340 Enter your expense (-1 for stop): 450 Enter your expense (-1 for stop): -1 So far you spent $ 790.0 You can buy more electronics. >>> ========= RESTART: C: \Users \Rita \Desktop \Lab5-1 B BudgetA Enter your available amount for electronics in 2020: 900 Enter your expense (-1 for stop): 730 Enter your expense (-1 for stop): 290 Enter your expense (-1 for stop): -1 So far you spent $ 1020.0 No more electronics in…

Python Coding-While Loops (In PyCharm Community edition) Create a while loop that SUMS up ALL the numbers given from an initial number and an ending number. Example would be : Input1 : What is the first number? 0 Input2 : What is the last number? 3 DO NOT SHOW but these are the computations inside the code : 0 + 1 + 2 + 3 = 6 This is the Output : The sum of all the number from 0 to 3, is 6 In the code you are going to use a total variable and add each additional time it runs through the loop to that total. REMEMBER the assignment from the first unit of programming where we used this formula : BUT you are going to create your own method using a while loop to emulate what formula accomplishes WITHOUT using this formula. The user will put in the first number and the last to be SUMMED - you will use the while loop to calculate all of the additions leading to the final number.
