Thank you! The same homework with different requirements(below). what is code? homework6 Reading data from a file into a list Ask user to enter file containing floating point numbersOpen and read file into a list of strings and assign to linesFor each line in lines Split the line into individual floating point numbers and assign to tokens Assign 0 to total Assign first number to smallest Assign first number to largest For each token in tokens Convert to a floating point number and assign to number Add number to total If number is less than smallest, assign number to smallest If number is greater than largest, assign number to largest Calculate average Display total, average, smallest number, largest number
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.
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…
Write a program that will input the contents of a text file containing integers then writes each number and the frequency of that number appearing in the file. The output should look like the following sample output: Number Frequency 1 2 3 3 Also, copy the contents of the text file under your code Hints: Sort the list in ascending order before counting the numbers.

This is phython not Java Lab: Write a file copying program. The program asks for the name of the file to copy from (source file) and the name of the file to copy to (destination file). The program opens the source file for reading and the destination file for writing. As the program reads each line from the source file and it writes the line to the destination file. When every line from the source file has been written to the destination file, it close both files and print “Copy is successful.” In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that both “add-copy.py” is identical to “add.py” because “add-copy.py” is a copy of “add.py”. Sample run: Enter file to copy from: add.py Enter file to copy to : add-copy.py Copy is successful. Source file: add.py print("This program adds two numbers") a = int(input("Enter first number: ")) b = int(input("Enter second number: ")) print(f"{a} + {b} = {a+b}") Destination…
