- Task. Your task is to develop a python program that reads input from text file and finds if the alphanumeric sequence in each line of the provided input file is valid for Omani car license plate. The rules for valid sequences for car plates in Oman are as follows: Each sequence is composed of 1 to 5 digits followed by one or two letters. Digits cannot start with 0, for instance, 00, 011, or 09 are not valid digit sequences. The following list are the only valid letter combinations: ['A','AA','AB','AD','AR','AM','AW','AY', 'B','BA','BB','BD','BR','BM','BW','BY', 'D',DA','DD','DR','DW','DY', "R',RA','RR','RM','RW','RY', 'S','SS', 'M', 'MA','MB','MM','MW','MY', W',WA','WB','ww, Y,YA','YB','YD','YR','YW','YY'] Program Input/Output. Your program should read input from a file named plates.txt and write lines with valid sequences to a file named valid.txt. Any line from the input file containing invalid sequence should be written to a file named invalid.txt. Each line from the input file must…Write a C++ program that reads the contents of (data.txt) file which contains 3- digit numbers, and then finds the number with the maximum digits summation and prints it with the summation on the screen. Example 1: data txt The number with maximum digits summation is 989 Digit's summation 26 455 657 121 356 909 957 989 459 789 878I am having trouble coding this in python: Develop 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…
- You have to collect information about the states in your country and then store each states’ name, size, population, Governor, and secret name in a file. Unlike other input, Secret name will be generated from states’ name in a separate method which change vowels alphabet of input string states’ name into the number as given in the following table. ( Table Attached----Table Attached----Table Attached) Write a python program to accept the data for a number of states from the keyboard and store the data in a file in the order in which they’re entered.Write a Python script that extracts and prints a single record from an input file in which the data is organized by line. Each line contains the name of a person (possibly containing multiple words) followed by the year of his birth. Abbas ibn Firnas ibn Wirda: 809 Muhammad ibn Musa al-Khwarizmi: 780 Abu Al-Walid Muḥammad Ibn Aḥmad Ibn Rushd: 1126 The program uses function extractDataRecord with the specification: @param infile the input text file object @return parts a list containing the name (string) in the first element and the year of birth (int) in the second element. If the end of file was reached, an empty list is returnedImplement the following programs in cpp code; Write a program to convert all the characters in uppercase in a file txt. Write a program to find a string “is” from a file txt. Write a program that takes input in 100 students(id, name, age, gender) and write their data in file student.txt and find from file how many students are of age 18. Write a program that takes input in 50 employees(id, name, salary, age) and write their data in file employee.txt and find from file salary of an employee with id 13.
- Use Python 3 for this question. Do the sentiment analysis based on a text file which contains numerous tweets in its raw text format. All tweets collected in this file contains a key word specified by the instructor. The key word being used is “Trump”. You can use the raw tweets file provided by the following link: tinyurl.com/46ntt3a5. You will need to convert this to a .txt file for this assignment. Your raw tweets file size at least needs to be 350K. After you have the raw tweets file ready, you need to perform the following tasks in a Jupyter notebook file. First you need to clean up the tweet file content to the best you can. For each word that is not a “stop word” (and, the, a, is, as, …), assign a value +1 for positive sentiment or a value -1 for negative sentiment. A list of “positive” words will be provided to you. You can easily find a list of “stop words”, and a list of “negative” words online. For the words that is not in positive/negative/stop words, count as ‘others’.…In Python: Build a function that takes a record from your FASTA file as an argument, and returns a count of each amino acid coded for by the codons of the sequence. Keep in mind that because these records are not necessarily in the proper reading frame, so the user should be prompted to select a reading frame (0, +1, +2). You should put some thought into the presentation of your results by your main function, making sure they are clear and readable. The fasta file contains the below: >MD10G1276500 pacid=40089867 polypeptide=MD10G1276500 locus=MD10G1276500 ID=MD10G1276500.v1.1.491…Using C programming language. Write a program that reads a text file, and calculates the frequency distribution of individual letters in the file. Upper and lower case letters are considered the same. Numbers and punctuation are ignored. The frequency value should be the percentage that particular letter occurs in relation to all letters. Thus, the output will have two columns, each row will show the letter, and it's frequency (neatly formatted). Your program should prompt for the file name, and handle the case where the file isn't found. Use at least one user defined function (even if it's trivial) that's defined in a separate file, and use a header file that contains the declaration.
- In a text file, I have two numbers each line. The numbers are the employee ID and the number of hours the employee work. My goal of this program is to read the both employee ID and the number of hours the employee work and print it out in the main program. If the list of employee id is not in order, sort it in order and still print it out in the main program. Additionally, after printing them out, print out the total number of employees and the total number of hours all the employee work. Write this in java For example File.txt EmployeeID Number of Hours Work 3 12 2 20 1 40 5 20 7 9 In the main program print: EmployeeID Number of Hours Work 1 40 2 20 3 12 5 20 7 9Using a text editor, create a file that contains a list of at least 15 six-digit account numbers. Read in each account number and display whether it is valid. An account number is valid only if the last digit is equal to the remainder when the sum of the first five digits is divided by 10. For example, the number 223355 is valid because the sum of the first five digits is 15, the remainder when 15 is divided by 10 is 5, and the last digit is 5. Write only valid account numbers to an output file, each on its own line.*Note that the contents of the file AcctNumsIn.txt will change when the test is run to test the program against different input.
