Textbook Question
Chapter 6, Problem 1PP
Write a
(Hint: Have your program read from the input file until it encounters the three characters #N#, and have it copy what it reads to the output file as it goes. When it encounters the three letters #N#, it then sends output to the screen asking for the name from the keyboard. You should be able to figure out the rest of the details. Your program should define a function that is called with the input- and output-file streams as arguments. If this is being done as a class assignment, obtain the file names from your instructor.)
Harder version (using material in the optional section “File Names as Input”): Allow the string #N# to occur any number of times in the file. In this case, the name is stored in two string variables. For this version, assume that there is a first name and last name but no middle names or initials.

Write a program that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade. Each row of the .txt file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student, each separated by a space. A sample of the student information is provided in StudentInfo.txt below. Assume the number of students is at least 1 and at most 20.
The program performs the following tasks:
• Read the file name of the .txt file from the user.
• Open the .txt file and read the student information using readline() or readlines().
• Compute the average exam score of each student.
• Assign a letter grade to each student based on the average exam score in the following scale:
◦ A: 90 =< x
◦ B: 80 =< x < 90
◦ C: 70 =< x < 80
◦ D: 60 =< x < 70
◦ F: x < 60
• Output the first names, last names, exam scores, and letter…
Write a program that reads student data from a file, compute their GPA and writes the results to a different file.
1. The user should have the option to either enter their text file that contains the student grades or use the provided text file that contains theinformation.
The data in "indata.txt" should look similar to this,
Lara_Croft75 70 91 69 89Chris_Redfield68 88 79 85 94Johnny_Cochran69 98 95 77 80Wanda_Maximoff84 86 98 95 92Luke_Skywalker74 96 80 98 97William_Kurt89 52 99 81 58Samuel_Jackson50 96 50 64 95END_OF_FILE
This is supposed to be in python. This is what I have so far. I have no experience I apologise. I am trying to finish the GPA calculating program currently but am having trouble finishing it.
grade = input("enter grades")points = 0
if grade is 90-99:total_points = 4.0if grade is 80-89:total_points = 3.0if grade is 70-79:total_points = 2.0if grade is 60-69:total_points = 1.0if grade is 50-59:total_points = 0.0gpa = total_points/len(grade)print(gpa,"is gpa")
consider a program that reads data from a text file called: "klingon-english.txt" (shown below). How would one construct such a program with the following conditions:
1. Ask the user to choose a Klingon consonant they want to practice with. Ask again if the user’s answer is not a valid Klingon consonant, until the user enters a valid consonant.
2. Find a Klingon word that starts with the chosen consonant (the text file contains only one word that starts with any given consonant, so you don’t need to use the random library)
3. Ask the user to translate the chosen word into Klingon
4. Print "Correct" if the user’s answer is correct
5. Print "Sorry, you’re wrong!" if the user’s answer is wrong
6. Print The correct answer is ... if all three user’s answers are wrong
You will also factor in this version:
7. If the answer is incorrect, show the first hint: the first and last characters of the correct Klingon word. When showing a hint, replace all other characters with a star (*)

Every name in the file consists of a first name and last name. Unfortunately, the programmer that created the file of names did not guarantee that each name was on a single line of the file. Read this file of names and write them to a new text file sorted according to first name, one name per line.

- Write a program that receives a coded message file(Lab3ExtraCreditCT.txt) from your local espionage agent and decodes it into a file using standard English. The problem is your agent forgot to tell you the key used to decode the message. Fortunately, this is a simple substitution code consistently using 1 alphanumeric character to represent another, this is case sensitive. All other characters are not substituted, so a space will always be a space, a – will always be a –, a @ will always be a @, etcetera. You may use the following table to help you, it contains the most common letters used in the English language in descending order.

- Write a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name (the key field), merge the information as shown below. File 1 and file 2 are supplied. Here is an algorithm to merge the data from two files: Read a line from each data file While the end of both files has not been reached While the end of both files has not been reached Write the line from file 1 to the output file and read a new line from file 1. Else Write the line from file 2 to the output file and read a new line from file 2. Write the remaining lines (if any) from file 1 to the output file. Write the remaining lines (if any) from file 2 to the output file.
