- Need a different function in python that reads the data file and round the code below (see attached image) def calculateTotal(Name, Item, Price, Quantity): total = round(Price * Quantity,2) return totalarrow_forwardUsing C++, create a program that reads integers from the file named "123456" and performs the following actions: Define a function named "calculateFileStats" that reads all the integers from the file and displays the following on the console: -The total sum of all numbers in the file -The minimum value of the numbers in the file -The maximum value of the numbers in the file -The average value with 2 decimal places. If the program fails to access the file, display an error message to the user and terminate the program. Close the file once you have finished reading it. Call the function "calculateFileStats" in main. Note: I did not forget to attach an input file. Use your own input code. I am interested in your code. sample run: Total: 30309 Minimum: 1 Maximum: 10 Average: 5.58arrow_forwardCreate a string variable containing your full name (with spaces) 2) print the string as shown below 3) Create a blank 5x10 character array 4) Create a function printArray() that will print every row and column of the array 5) Create a function getNextCharacter() that gets passed the name string and returns the next non-blank character. If you have reached the end of the string then continue at the beginning. You may need to use a global variable 6) Create a function fillArray() that will fill the 2 dimensional array with the letters of your name skipping blanks. Use the above getNextCharacter() function to fill the array with only the characters in your last name. 7) Print the entire array. 8) Request a row number to print and use a sentinal loop to make sure the row number is valid. If not then request a row number again 9) Create a function printIter() that prints only the passed row using iteration 10) Create a function printRecur() that prints only the passed row using recursion…arrow_forward
- python Now write another program that reads the text file created in the program above and calculates the user's weekly pay. The program should begin by prompting the user for the regular hourly pay rate. The program should then loop through the file and report the days and hours worked. The program should finish by calling a custom void function named calc_pay that calculates and prints the weekly pay, including overtime, if applicable. By law, weekly hours in excess of 40 should be paid at 1.5 times the regular hourly rate. The calc_pay function takes two arguments, total hours and hourly pay rate, and it must be imported from a separate module file. Note that three outputs are required for the pay.Sample Output 1Enter your hourly pay rate 25.00Here are your hours this weekMonday hours : 10.0Tuesday hours : 8.0Wednesday hours : 12.0Friday hours : 12.0Saturday hours : 8.0You worked 50.0 hours this weekYou worked 10.0 hours overtimeYour hourly pay rate is $25.00 Regular pay :…arrow_forwardIn pseudocodearrow_forwardpython please! the first answer i received didn't check out. it is graded by a computer on autolab. im so confusedarrow_forward
