Write in Python Write a function named max that accepts two float values as arguments and returns the value that is the greater of the two. For example, if 7.2 and 12.1 are passed as arguments to the function, the function should return 12.1. Use the function in a program that prompts the user to enter two float values. The program should display the value that is the greater of the two.

Write a function that has a single input argument grade. If the user's input is a numeric number, the grade letter should be displayed to the command window depending on the value of grade, as shown in the table below. Otherwise, MATLAB should stop the execution and send an error message: "invalid input" to the command window.

Create shell script to calculate total loan amount .Display the number of long term loans. Input the name of bank and number of loan. If the number of loans is five(5),user will enter (5) loan amounts. Based on the loan amount entered ,program should be able to count number of long term loans. The classification is as follows Loan amount >= 16000 Long Loan amount >= 7000 and <=16000 medium Loan amount <= 4000 Short
Write a function myfunction that requests user input i the form of an integer value, 1, 2 or 3. The function should print out: 1. Option 1 selected 2. Option 2 selected 3. Option 3 selected when the corresponding number is entered, and the loop should end if q is entered. Any unrecognised options should result in the following statement being printed: • Unknown option
Program: final.py Specification First, download the template file, final.py. This file contains the function names and documentation. You are required to add a header comment block with your name, the file name, the current semester, and year. Do not change the function headers, just add your implementation for each function where indicated. Add descriptive comments to your code. Remember to indent all the code for the function. Here are the functions that you will write: • Calculating tips is a common operation and the first function you write for the final project will do exactly that. The function calculate_tip accepts two parameters, the bill amount and the percent to tip, and returns the amount of the tip to write into the bill. The function should return the string "Invalid charge amount" if the charge is not more that 0 and "Invalid tip percent" if the tip is less than 0. Function heading: def calculate tip(charge, tip_percent): Parameter Specification: charge is the total ch…
Write a Python program that contains multiple user-defined functions which calculate storage requirements and costs. These functions will provide useful metrics in the context of data storage and backup solutions. Perform the following steps: Create a function named calculate_backup_size that takes two arguments: data_size (in gigabytes) and backup_frequency. This function should return the data_size multiplied by backup_frequency, representing the total storage needed for backups in a week. Create another function named calculate_storage_cost that takes two arguments: backup_size and cost_per_gb. This function should return the value of backup_size multiplied by cost_per_gb, representing the total cost for the backup storage. Create a third function named storage_info that takes four arguments: data_size, backup_frequency, cost_per_gb, and weeks. This function should call calculate_backup_size and calculate_storage_cost functions, taking the appropriate arguments. Then it should…
1)Write a shell scriptthat calculate electricity bill.The rates of electricity per unit are as follows: Consume-units>=300 then cost is Rs. 2 per unit Consume-units>300 and <=500 then cost is Rs. 5 per unit Consume-units>500 then cost is Rs. 7 per unit. 2)write a shell script that inputs Salary and Grade. It adds 50% bonus if the gradeis greater than 15. It adds 25% bonus if the grade is 15 or less and then display the total salary. 3)write a shell script that inputs three number and display the maximum number.E
Create the following, in Python: You have a business that cleans floors in commercial space and offices. You charge customers $0.45 per square yard, and some customers require multiple cleanings every month. You need two custom functions for your business. The first function takes a floor's length and width in feet and returns the area in square yards. The second void function takes the area, charge per square yard, and number of monthly cleanings as arguments and prints the cleaning cost. This latter function uses selection (if...else) logic to print different output for single and multiple monthly cleanings (see Sample Outputs). Use a properly named constant for the charge per square yard, too.
