Python Write a program that first reads in the name of an input file and then reads the file using the csv.reader() method. The file contains a list of words separated by commas. Your program should output the words and their frequencies (the number of times each word appears in the file) without any duplicates. Ex: If the input is: input1.csv and the contents of input1.csv are: hello,cat,man,hey,dog,boy,Hello,man,cat,woman,dog,Cat,hey,boy the output is: hello 1 cat 2 man 2 hey 2 dog 2 boy 2 Hello 1 woman 1 Cat 1 my code is not working, this is what i have: import csv # to store words words= [] # openfile with open('input1.csv') as f: for row in csv.reader(f, delimiter=','): # read data, add to words words += row # get unique words unique_words = sorted(set(words), key=words.index) for word in unique_words : # print words followed by space then its count print(word , words.count(word), end =" ") # formatted output at end print("")

Java 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…

Suppose 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.

Problem A straight line can be defined by a pair of points p1(x1, yı) and p2(x2, y2). The slope m of a line is defined as follow: У2 — У1 m = X2 - X1 Your program reads the points from a text file called 'points.txt’ which contains the coordinates of unknown number of pairs of points as shown in Figure 1. Each line contains four values x1, y1, x2, y2, where x1, yl are the coordinates of the first point and x2, y2 are the coordinates of the second point. 10 -2 7.5 -3.2 4 15.5 -4.6 21 -2 Зр 12.5 6. 2 5 -3 -6 10 3 10 15 Figure 1.
