How do you create an object for reading data from file test.txt? How do you create an object for writing data to file test.txt?
You are given a filename. Read the names in the file and output only the initials. For example, if the filename is "data.txt", and the file content in "data.txt" is Dumond, Kristin Larson, Lois the output should be: KD LL
Make the following modifications for the solution above: name the output/input file "myRandomNumbers.txt" use a loop to output 17 random numbers to the file after creating the file, close it open the file for input and read the contents and then total the numbers in the file determine the average of the numbers in the file determine the highest and lowest numbers in the file DO NOT USE PYTHON BUILTIN FUNCTIONS TO CALCULATE THE AVERAGE OR THE HIGHEST AND LOWEST NUMBERS an expected number of modules/functions would be in the 5-8 range Display your results: the numbers generated on a single horizontal line the calculated total and average the highest and lowest number in the file Be sure to use clear prompts/labeling for input and output.

For this task, you are to write code that handles the transfer of virtual coins between players in a video game. Instructions As this task relates to tranferring coins between players, a Player class has been provided, which supports adding and subtracting coins. Also provided is an interactive loop for testing the transfer of coins between players. Part A You are to write a function called transfer_coins with three parameters: the number of coins to transfer, the player from which coins will be taken (the "giver"), and the player which the coins will be given to (the "receiver"). It should use the appropriate instance methods on each of the player objects to update them as required. Part B If you tested your solution thoroughly in the previous part, you probably came across a logic error in the program---there's nothing to stop us from taking more coins from a player than they have! You are to fix this problem by raising an exception instead of completing the…
Exercise Write the pseudo code and flowchart that will read a file of student test results and produce a student test grade report. Each test record contains the student number, name and test score (out of 50). The program is to calculate for each student the test score as a percentage and to print the student's number, test score (out of 50) and letter grade on the report. The letter grade is determined as follows: A = 90-100% B = 80-89% C = 70-79% 90-100 80-89 :A :B D = 60-69% E = 0 -59%
Run the program below, which creates “Dates” in the HW library. You will need to change the input statement to account for the format of the raw data. Add the following to this data step: Using the yrdif function to add a variable called “Agetoday”, which is the age today. Use proc print to list all the variables to the output window. Remember to format all dates for output purposes. data HW.dates; input Subj $ DOB ; datalines; 001 11Nov06 002 25May07 003 25Dec06 ; run; proc; run;
Computers are widely used for survey data analysis to compile and analyze the results of survey and opinion polls. Show in the table below are the 99 response ratings (values from 1 to 9) from reviewets for a beta website: (See attached photo (table)) Write a program that computes the mean, median, and mode of the 99 values. Please refer to the sample run shown below, and follow the display output. (See attached file for sample run)
Write a program that will take in basic information from a student, including student name, degree name, number of credits taken so far, and the total number of credits required in the degree program. The program will then calculate how many credits are needed to graduate. Display should include the student name, the degree name, and credits left to graduate. Step 4: Write the exact output you would expect from the following line of code if the user of the program enters “Bill Jones”. (Reference: Displaying Items, page 40 – 41). Display “The student’s name is “, studentName
python Now write another program that reads the text file created in the program above and calculates the user's weekly pay. The program should begin by prompting the user for the regular hourly pay rate. The program should then loop through the file and report the days and hours worked. The program should finish by calling a custom void function named calc_pay that calculates and prints the weekly pay, including overtime, if applicable. By law, weekly hours in excess of 40 should be paid at 1.5 times the regular hourly rate. The calc_pay function takes two arguments, total hours and hourly pay rate, and it must be imported from a separate module file. Note that three outputs are required for the pay.Sample Output 1Enter your hourly pay rate 25.00Here are your hours this weekMonday hours : 10.0Tuesday hours : 8.0Wednesday hours : 12.0Friday hours : 12.0Saturday hours : 8.0You worked 50.0 hours this weekYou worked 10.0 hours overtimeYour hourly pay rate is $25.00 Regular pay :…
