In Python Initially, you will prompt the user for the names of two files: one will contain Customer information, and the other will contain Product information, as described below. Sample files are attached (below) to this project so you can download and review them. Some test cases may use other files, which you will not be able to see, so it is important that your program ask the user for the file names, and be able to open and read any file. The Customer Information file will be a csv file, with no header row, in which each line has the following fields, which are separated by commas. Customer_Number Customer_Name Customer_Balance Customer_Password For example, the sample file named customers.csv has several lines, and the first two are: 24155,"Carey, Drew Allison",838.41,Bo7&J 24426,"Butler, Geoffrey Barbara",722.93,Ep5& The Product Information file will be a csv file, with no header row, in which each line has the following fields, which are separated by commas:…

Note: Please answer the question in Python only: Citizens of Byteland play the game regularly. They have blocks, each of which represents some integer from 0 to 9. These are arranged together in a random fashion without having to remember that the first block is never 0. Once they form a number, they are read in reverse order. check that the number and its reverse are the same. If both are the same, the player wins. Such numbers are called palindromes. Ash happens to see this game and wants to simulate it on the computer. As a first step, it wants to take input from the user and check if the number is a palindrome and declare whether the user wins or not. Input 1 666 Output wins
IN Python Code Only Jessie has a lot of cooking with her (N). He often remembered the first few letters of the recipe and forgot the others. Like all great chefs, Jessie re-calculated the recipes according to the priority. So, looking at the list of recipes and priorities answers Jessie's questions. Response from Jessie: Giving the first few letters of the recipe; you have to print the perfect recipe in the most important way. Note: Every recipe has a unique value. Input 1 flour-with-eggs 100 1 G Output 0
PYTHON: Consider the following problem: A city council has placed 360-degree cameras to monitor activity at a selection of locations (car parks, bus stations, etc.) across the city. Solve the problem of finding the smallest set of locations where to place cameras so that each location either has a camera or is at most 25 metres from a camera. A. Sketch an algorithm (don't write code) to solve the original problem, by generating all subsets of locations and for each subset checking if putting cameras at those locations will cover all locations.Your algorithm does not need to specify how the subsets are generated.Your algorithm can use the 'full coverage' function.The solution should be the smallest subset that covers all locations. B Analyse the worst-case complexity of your algorithm.
On Thursday, November 4, 2021, Big Man Games wrote: Computer programs are great at computing mathematical formulas. Once the formula is properly encoded you can use the code as much as you want without reprogramming it and you can share it with non-programmers without any trouble. This lab is an example of such a formula. Once you program it you won’t have to worry about the area of a circle again. Write and test a program that computes the area of a circle. This program should request a number representing a radius as input from the user. Use the formula 3.14 × radius2 to compute the area. Tip: There are a couple of ways to code an exponent. Look in the Operators unit for help (and you can’t use an x for multiplication). Tip: You will need to use the float data type to compute the remainder. The output should explain the results. Don’t just print a number. Tip: For your print statement you will need to use the comma, “,”, or plus, “+” symbols to stitch your output together. (“The…
Welcome to the era of Aladdin and the great magic lamp. This is 1st of January and Aladdin will be in jail for one year. He was recently caught for helping forty thieves. Now he has nothing to do. But he knows that Jasmine is waiting for him. At some point he got an idea to give Jasmine a magical program that can find intervals of months from a year. This allows her to easily determine how long it will take for Aladdin to get out. Then Aladdin rubs the magic lamp and The Genie appears. Then he asked The Genie to make such a magical program. Unfortunately the Genie doesn't know programming and he wants your help to create that magical program. Genie will give you N as the day of the year and you have to print in which month that day is. Input Format Input will contain one line with a single integer N, day of the year. Constraints 1 <= N <= 365 Output Format Print a single line containing the name of month. Be careful about the newline ('\n') at the end. Sample Input 0 1 Sample…

Please do it in python I have asked this question before but i need it in try and except You have been asked to take a small icon that appears on the screen of a smart telephone and scale it up so it looks bigger on a regular computer screen. The icon will be encoded as characters (x and *) in a 3 x 3 grid as follows: Write a program that accepts a positive integer scaling factor and outputs the scaled icon. A scaling factor of k means that each character is replaced by a k ? k grid consisting only of that character. Input Specification: (Use a try and except here)The input will be an integer such that 0 < k ≤ 10. Output Specification:The output will be 3k lines, which represent each individual line scaled by a factor of k and repeated k times. A line is scaled by a factor of k by replacing each character in the line with k copies of the character. Use try and except
In Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
