python file by using read write append delete in same programing file

USE PYTHON Python already supports math, whereby you can write code to add, subtract, multiply, or divide values and even variables. But let’s write a program that enables users to do math, even without knowing Python. In a file called interpreter.py, implement a program that prompts the user for an arithmetic expression and then calculates and outputs the result as a floating-point value formatted to one decimal place. Assume that the user’s input will be formatted as x y z, with one space between x and y and one space between y and z, wherein: x is an integer y is +, -, *, or / z is an integer For instance, if the user inputs 1 + 1, your program should output 2.0. Assume that, if y is /, then z will not be 0. Note that, just as python itself is an interpreter for Python, so will your interpreter.py be an interpreter for math! Please see 2 attached photos for demo and Test program. **USE PYTHON** THANKS

1 Goals Use C++ to read data from a text file and create an array of numbers. Use the C++ 'fstream' library functions to open, read and close a text file. You can use the C++ 'iomanip' library to format your output and manage whitespace on your input. Graduate students must create and write the data to a new text file. 2 Your assignment is to create a program that does the following: a. You will need to create a new file (you can do this in the file system – make it plain text) and call it mydata.txt. b. Put a column of numbers in the text file to read later. Pay attention to type – make them all have decimal points. In repl.it, use the numbers in my file. c. Based on the examples in the slides (L3) and the textbook, write a C++ program, include 'iostream' and 'fstream'. You might need 'iomanip'. d. Your program should read the numbers from the file into an array and print the array to the console in reverse order using a for loop. e. Graduate Students must also print the output to a...

*Code in Python The Payroll Department keeps a list of employee information for each pay period in a text file. The format of each line of the file is the following: <last name> <hours worked> <hourly wage> Write a program that inputs a filename 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: An employee’s name The hours worked The wages paid for that period. An example of the program input and output is shown below: Enter the file name: data.txt Name Hours Total Pay Lambert 34 357.00 Osborne 22 137.50 Giacome tti 5 503.50
