Python - Next Birthdate
In this task, we will write a program that reads birthdate data from a given CSV file, and given the current date, determines which person's birthday will be celebrated next.
Create a function with the following signature:
nextBirthdate(filename, date)
filename: parameter, which represents the CSV filename.
date: parameter, which represents the current date.
The function should open the CSV file, read the birthdate data, and determine which person's birthday will be celebrated next, given the current date. The name of the person should be returned. In other words, given a date, find the person whose birthday is next.
Sample Run
birthdates.csv

Write a program to implement the algorithm that you designed in Exercise 20 of Chapter 1. (Assume that the account balance is stored in the file Ch4_Ex15_Data.txt.)
Instructions to Exercise 20 of Chapter 1 have been posted below for your convenience.
Exercise 20
An ATM allows a customer to withdraw a maximum of $500 per day. If a customer withdraws more than $300, the service charge is 4% of the amount over $300. If the customer does not have sufficient money in the account, the ATM informs the customer about the insufficient funds and gives the customer the option to withdraw the money for a service charge of $25.00. If there is no money in the account or if the account balance is negative, the ATM does not allow the customer to withdraw any money. If the amount to be withdrawn is greater than $500, the ATM informs the customer about the maximum amount that can be withdrawn. Write an algorithm that allows the customer to enter the amount to be withdrawn. The algorithm then checks the…
8.In this exercise you will create a program that will be used in a digital library to format and sort journal entries based on the authors last name. Each entry has room to store only the last name of the author. Begin by removing the first name "Isaac" from the string variable journal_entry_1 by using the string function erase. Do not forget to also remove the whitespace so that the string variable journal_entry_1 will then contain the string "Newton" with no whitespaces. The journal entries should be sorted alphabetically based on the authors last name. For example, the last name "Brown" should come before the last name "Davis" Create an if statement so that if the last name contained within journal_entry_2 is alphabetically less than the last name contained within journal_entry_1, then the string values are swapped using the string function swap. You may use either of the comparison operators < > in the if statement but remember that following ASCII, "A" is lexicographically…

- The function print_last_line in python takes one parameter, fname, the name of a text file. The function should open the file for reading, read the lines of the file until it reaches the end, print out the last line in the file, report the number of lines contained in the file, and close the file. Hint: Use a for loop to iterate over the lines and accumulate the count. For example: Test Result print_last_line("wordlist1.txt") maudlin The file has 5 lines.arrow_forward9.Code please.

- 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.

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.
