Write a program to read the file "input.txt", which contains one student's name for one line, such as John Karl Tom You need to output them together with the line number of each name to the file “output.txt", such as 1, John 2, Karl 3, Tom At last, you also need to output the total number of students, such as printing out The total number of students is xxx. (xxx is 3 with the above case) Please include appropriate checks on the opening of the file.

Your program should use a loop to read data from a text file which contains students' names and 3 exam scores. The program should calculate the exam average for each student, determine the appropriate letter grade for that exam average, and print the name, average, and letter grade. After printing all this, you need to print the count of the total number of A's, B's, C's, D's, and F's for the whole class. The text file you need to use can be accessed using this link: scores.txt. Copy this file to the folder where your program will reside. The text file contains a list of 30 records, and each record contains a name and that person's 3 test scores. Each field is separated by a tab character. The first 2 records looks like this: Davis 88 92 84Wilson 98 80 73 and so on. Your program will need to open this file and read each line until the end of file. I recommend calculating a student's exam average and letter grade as you read the file, although this is not a…

The pressure of a gas changes as the volume and temperature of the gas vary. Write a program that uses theVan der Waals equation of state for gas, to create a file that displays in tabular form the relationship between the pressure and the volume of n molesof carbon dioxide at a constant absolute temperature (T). P is the pressure in atmospheres, and V is thevolume in liters. The Van der Waals constants for carbon dioxide are a = 3.592 L2 · atm/mol2 and b = 0.0427L/mol. Use 0.08206 L · atm/mol · K for the gas constant R. Inputs to the program include n, the Kelvintemperature, the initial and final volumes in milliliters, and the volume increment between lines of the table.Your program will output a table that varies the volume of the gas from the initial to the final volume insteps prescribed by the volume increment. Here is a sample run:

A python function opens file data.csv, reads the data from the file and spits the data into three columns, x, y and z. The data is then printed out. Function: f = open("data.csv ", "r") print('x\ty\tz'.format()) for row in f: temp = row.split(',') for cell in temp: print(cell,end='\t') print() data.csv contains: 1.2,2.1,1.1 2.3,3.2,0.6 0.7,1.9,0.1 1.8,2.5,0.3 4.6,2.7,0.9

Below this question is a generated text representing a DNA sequence. The first line starts with '>' and is a comment, and the lines after that hold the sequence. The sequence has letters 'A', 'C', 'T', and 'G'. In your program (written in python) for this question, read the sequence using the statements: f = open('kdpF.txt') # opens a file for reading line = f.readline() # reads a single line print(line) seq = ''for line in f : # reading the rest of the lines seq = seq + lineseq = seq.replace('\n', '') # removing the newline characters seq = seq.upper() print(seq) def gcContent(sequence) : # You do the rest pass Also write a function gcContent(sequence), which returns the percent of the sequence which is either 'G' or 'C'. Use your function on the input sequence and print the results. generated text DNA sequence: >200 bp region of the chromosome of E. coli, containing gene kdpF, shortest…
Consider a CSV file contains information about COVID-19 status of Bangladesh. The header of this file is "Date", "District", "Effected Today", and "Recover Today". Write a java program to find the minimum of the "Effected Today" and the maximum of "Recover Today" column from the file. Example: File contains: Output: Effected Today: 27 Recover Today: 195 18/6/2021, DHK, 345, 195 18/6/2021, BOG, 75, 28 18/6/2021, CHT, 231, 68 18/6/2021, KHL, 27, 17
In python The text file “studentMarks.txt” has been provided for you. Each line contains the Last Name, First Name and 8 marks separated by spaces of a single student. For each student in the file, adjust the file to include the average of their top 6 marks, rounded to 1 decimal place, at the end of the line. For example, in the file, the line may say: Mars, Bruno 82 82 85 94 65 79 81 90 Afterwards, it should be updated to say: Mars, Bruno 82 82 85 94 65 79 81 90 Top6Avg: 85.7 Your program must define a function to determine the average of the top 6 marks. You may define more functions as needed for your program.
