For this HW assignment, you will demonstrate that you can write data files. Python program will you write data to a file. The specific requirements for each program are:1) The first program will use the code that is contained in HW12-WriteStart.py to create thedata to be written out. Please feel free to examine the code provide but do not modify thecode. Place your code below the comment that says to place your code below this line. Thecode you should add should do the following:a. Specify a default file name to use for the output file.b. Check to see if the file already exists. If it does already exist, ask the user if it is okayto overwrite the file—be sure and tell them the file name. For an extra challenge andbonus points, prompt the user to enter a new file name.c. The data created by the initial code in HW12-WriteStart.py creates a list named Rowsthat contains rows of data. Each element of Rows is another list that contains a nameand some quiz scores. You are to write each row of…

Programming Problems Note: Please note that the doctest file uses random.seed. This guarantees that any numbers generated by the random module will be exactly the same each time. If you use the minimum (and correct) calls to the random function, your output should match the doctest exactly. If you make extra calls to random, then they will not match. interleaved Write a function interleaved that accepts two sorted sequences of numbers and returns a sorted sequence of all numbers obtained by interleaving the two sequences. Guidelines: • each argument is a list assume that each argument is sorted in non-decreasing order (goes up or stays the same, never goes down) you are not allowed to use sort or sorted (or any other form of sorting) in your solution • you must interleave by iterating over the two sequences simultaneously, choosing the smallest current number from each sequence. Sample usage: 1 >>> interleaved( [-7, -2, -1], [-4, 0, 4, 8]) 2 [-7, -4, -2, -1, 0, 4, 8] 234 >>>…

URGENT  In python You just started your summer internship with immunityPlus based in La Crosse, Wisconsin. You are working with forecasting team to estimate how many doses of an immunization drug will be needed. For each drug estimation, you will be provided the following information: 1. The size of the target population 2. The life expectancy, in yeras of an individual in the population 3. A file containig ages, in years, of a sample of 12 people infected in the population To calculate the number of doses needed: 1. Calulate the average age of infection from a sample of 12 years 2.  Calculate the Base reproduction number(Ro) Ro = life expectancy / average age of infection 3. Calculate herd immunity threshold (Q) Q = 1 - 1/Ro 4. Calculate the numebr of doses Doses = Q * population size Construct a profram that allos a user to enter the size of the target population, the life expectancy of an individual in the population, and the name of the sample file. Once this information is…

Objectives Practice defining functions with parameters. Practice manipulating strings. Implement your own version of Python string methods The provided file string_functions.py defines several string functions, but does not include the code for them. Add code to implement functions that are equivalent in behavior to the corresponding built-in Python string function. Every function MUST return a value. Use loops to implement your functions. You cannot use built-in string methods, string functions, or string-operators to implement your functions. Each function is worth a maximum of 10 points. 1. cs110_upper: Takes a string as a parameter and returns it as a string in all uppercase. Hint: Use the ord () function to get the ASCI value of a character. For example, ord ('a') returns the integer 97. You will also need to use the chr (value) function that returns a string of one character whose ASCII code is the integer valus. For example, chr (97) returns the string 'a'. You cannot use the…

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:…

Write a script file that will ask the user for an integer. Your program must use the “mod” function to find all the composite numbers up to and including the number input by the user. You cannot use the “isprime” function in MATLAB. You must use a nested loop and the “mod” function to determine the composite numbers.This program will find all the composite numbers up to and including the integer you input. Please input an integer: 11 4 is a composite number! 6 is a composite number! 8 is a composite number! 9 is a composite number! 10 is a composite number!

Add a function to get the CPI values from the user and validate that they are greater than 0. 1. Declare and implement a void function called getCPIValues that takes two float reference parameters for the old_cpi and new_cpi. 2. Move the code that reads in the old_cpi and new_cpi into this function. 3. Add a do-while loop that validates the input, making sure that the old_cpi and new_cpi are valid values. + if there is an input error, print "Error: CPI values must be greater than 0." and try to get data again. 4. Replace the code that was moved with a call to this new function. - Add an array to accumulate the computed inflation rates 1. Declare a constant called MAX_RATES and set it to 20. 2. Declare an array of double values having size MAX_RATES that will be used to accumulate the computed inflation rates. 3. Add code to main that inserts the computed inflation rate into the next position in the array. 4. Be careful to make sure the program does not overflow the array. - Add a…

Please use python and python file i/o to solve the problem. Create an input file input3_1.txt as shown below, solve the problem and print the output to output3_1.txt file as shown in the question.
