Can someone help me finish this code? I believe I have most of it but I'm stuck.

Here are the assignment instructions:

Create a Python program that:

• Opens a file and reads the contents of the following file
  • trips.txt
    • The file contains several lines of data, with each data item separated by commas. The data is:
      • A trip date
      • The amount of fuel used on the trip
      • The number of miles traveled on the trip
    • For each of the lines of data in the file, separate the data items and put them in appropriate variables
      • The file contents are in the form of strings, so you must convert the numbers in the data into the proper type
• Create a function that calculates the fuel mileage achieved on each trip
  • Pass the appropriate data to this function
  • Place this function in a separate module
  • Call the function as needed and have the function return the calculated fuel mileage
• Create a function that displays the following items on a single line, and place the function in the same module as the previous function.
  • Pass the appropriate data to this function
    • Trip data
    • Amount of fuel used
    • Numbers of miles traveled
    • Fuel mileage calculated for the trip
  • Call the function as needed to display the data items
• Create a new file to save the data read and the fuel mileage calculated for the trip
  • Write the data on separate lines for each trip in the data, with each item separated by commas
  • Remember that all of the data must be saved in the string form

The program should:

• Use variables with meaningful names
• Name the module containing the functions "SupportMod.py"
• Import the module into your program
• Display easily understood prompts when collecting user input
• Prompt the user for the name of the file to read the data from, and the name of the file to store the revised data
• Have appropriate comments indicating what each part of the program is doing
• Have a comment area at the beginning of the program identifying the author of the program and the class it was created for

Save the program and module with the functions as a Python modules, save them in zip file form, and submit the zip file through this assignment.

Here is the code I have so far:

'''Add module with functions to be used in this program''' import SupportMod

'''Variables''' readFileName = "" writeFileName = "" tripDate = "" tripMiles = 0.0 tripFuel = 0.0 tripMileage = 0.0 commaPosition = 0 lineLength = 0

'''File Handling''' readFileName = input("Please enter the name of the file you with to open: ") writeFileName = input("Please enter the name of the file you wish to creat: ")

readFileName += ".txt" writeFileName += ".txt"

readFile = open(readFileName, "r") #Open the file to read from it writeFile = open(writeFileName, "w") #Open the file to write to it

'''Loop to read from the file, extract the data, perform the computation, display the results, and write the results to a file.''' for line in readFile: commaPosition = line.find(",") #Find the first comma in the file line read lineLength = len(line) #Get the length of the file line read tripDate = line[0:commaPosition] #Extract the first data item from the line read line = line[commaPosition + 1: lineLength] #Slice the line string

commaPosition = line.find(",") #Find the next comma in the line read tripFiel = float (line[0:commaPosition]) #Extract the second data item from the line read

tripMiles = float (line[commaPosition + 1: lineLength]) #Slice the line string

tripMileage = SupportMod.Mileage(tripFuel, tripMiles) #Calculate the fuel mileage for the trip

SupportMod.ItemDisplay(tripDate, tripFuel, tripMiles, tripMileage)

writeFile.write(tripDate + "," + str(tripMiles) + "," + str(tripFuel) + "," + str(tripMileage)) format(tripMileage, ".2f") + " ") #Write the data items to the new file
