- Currently working with python and I have imported an excel file into my code. I have a Header with the Name: Operation Index with 82 rows, with numbers between 50 and 150. I need help in writing a code in python that will count the number of rows where Operation Index is greater than 130.arrow_forwardHi, i need help with this program using Java. Write a program that reads the file AdventuresInWonderland.txt one line at a time and prints the count of each of the five vowels followed by a count of the consonants in the file. Coding requirements: Read the text from the file AdventuresInWonderland.txt. Use a single while loop to read the lines of the file. Use a single for loop to iterate over the characters in each line. Use a single switch statement to determine which counter to increment. Notes: The input may contain punctuation and digits as well as letters. Account for both uppercase and lowercase letters. Character.toLowerCase(ch) returns the lowercase character corresponding to ch(char ch). Character.toUpperCase(ch) returns the uppercase character corresponding to ch(char ch). Character.isLetter(ch) returns true when ch is an alphabetic letter Expected output: Vowels found: a: 324 e: 455 i: 251 o: 300 u: 109 Consonants: 2384 Example: If one creates a Scanner as…arrow_forwardhelp make new code on this python problem.arrow_forward
- The language is Javaarrow_forwardI need to create a program with python that will generate a password using a domain name the user has inputted. It will then use an algorithm that will alphabetize the domain name, capitalize all vowels, and add a number at the end the length of a domain name. I need to use loops and selection structures to implement the algorithm. The end will look like this: facebook>AbcEfOOk8 amazon>AAmnOz6arrow_forwardIn 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:…arrow_forward
- Python Create a program that reads the file (create a paragraph in a file). It should analyze each character of the file. For output, it should produce a well-formatted table indicating: The total number of printable characters The total number of capital letters The total number of lowercase letters The total number of numbers The total number of sentences (which end in a period) The total number of paragraphs (which end in a newline) Since the lab is an exercise in strings, you must use at least TWO different string methods to required information. And each stastic will need its own function.arrow_forwardjust do the first step. and the program should be in python and includ as many different functions as possible .arrow_forwardJava Your program must read a file called personin.txt. Each line of the file will be a person's name, the time they arrived at the professor's office, and the amount of time they want to meet with the professor. These entries will be sorted by the time the person arrived. Your program must then print out a schedule for the day, printing each person's arrival, and printing when each person goes in to meet with the professor. You need to print the events in order of the time they happen. In other words, your output will be sorted by the arrival times and the times the person goes into the professor's office. In your output you need to print out a schedule. In the schedule, new students go to the end of the line. Whenever the professor is free, the professor will either meet with the first person in line, or meet with the first person in line if nobody is waiting. Assume no two people arrive at the same time. You should solve this problem using a stack and a queue. You can only…arrow_forward
- I know you are using Al tools to generate answer but I don't want these answers. If I see Al or plagiarism in my response I'll definitely reduce rating and will report for sure. So be careful. I'll take serious action. Scenario involving a list of books stored in a file named "Books.txt." Create a Python program that performs the following tasks: Output all books in your list. Output books published between the years 2015 and 2020. Calculate the average rating of all books. Create a histogram of the number of books in each genre. Each element in the histogram should represent the count of books in a specific genre. Take all the books in "Books.txt" and store them in a Python set. Output all unique authors of the books. Output the total number of entries in your set. Books.txt: "The Silent Observer," 2018, Mystery, Emily Williams "Beyond the Horizon," 2016, Fantasy, David Thompson "Code Breakers," 2019, Thriller, Sarah Miller "Infinite Realms," 2017, Sci-Fi, Mark Anderson "Whispers of…arrow_forwardSuppose you are given a text file that contains the names of people. 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. For example, if the input file contains Ed Marston Bob Jones Jeff Williams Fred Charles The output file should be Bob Jones Ed Marston Fred Charles Jeff Williams Use arrays to solve the problem.arrow_forwardPlease help me with this question to built it in python. Your company keeps a list of employee information for each pay period in a text file. The format of each line of the file is following: <name>, <rate>, <hours worked>. Write a program that inputs a file from the user and prints to the terminal a report of the wages paid to the employees for the given period. The report should be in tabular format with the appropriate header. Each line should contain employee's name, the hours worked, and the wages paid for that period.arrow_forward
