Create a Program to Implement Vinyl-Record-System in Python Assignment Solution.


Write a program to implement vinyl-record-system in python language.

Requirements and Specifications

For this assignment, my class is using an excel file with a list of the inventory of music media, band names, songs,release dates, and conditions that they are in.
Source Code
Chapter 12: working with files
Name: Maxwell Sabel
File: ch12_vinyl_record_v5.py
Course: CIS 156, CGCC
import datetime # this module helps us get the current year
import csv # here we are bringing in a library that helps read files
# Part 1: as in previous weeks, you'll need to edit these next lines to find and place your files
# Use a file manager to see the full path of this file, then edit the text string inside the
# single quotes to match your system.
# Leave the leading lowercase r in place (this tells Python not to react to the symbols in the text)
# I happen to be using a directory called CIS156 under Documents.
# What you see below is on a Windows system... on a Mac this might look like
# r'/Users/david/Documents/CIS156/ch12_spring_2021_input_inventory.csv'
# Please keep the actual filenames (ch12_spring_2021_input_inventory.csv and ch12_report.txt) unchanged.
INPUT_FILE = r'C:\Users\sabel\OneDrive\Desktop\ch12_spring_2021_input_inventory.csv'
OUTPUT_FILE =r'C:\Users\sabel\OneDrive\Desktop\ch12_report.txt'
# Modify above... incorporate os module as described in this week's chapter and make these file names a bit easier
# to find no matter what operating system you're on.
# Note: don't get hung up here... get all the other Parts working, then come back if you have time and interest
# in adding the os module.
# Part 2 - complete the following function
def read_inventory_from_a_file(in_filename):
    """Gets our inventory, returns a list of (you decide)
    arg1 in_filename (string): a valid filename
    returns: a list (You decide what the list is... could be a list of Vinyl_Record objects(Ch9), could be a list of lists (Ch8) - your choice
    csv File format: text only .csv file with the following format:
        Title,Artist,Year Released,Condition (no spaces between). The first row is a header.
        Title and Artist are plain text
        Year released is plain text
        Condition is a few word description in plain text. Examples: scratched, near-perfect, warped
    Return: a list of (you decide)

def today_timestamp():
    """Get today's date and time, return as a string"""
    currentDT = datetime.datetime.now()
    return currentDT.strftime("%a, %b %d, %Y, %I:%M:%S %p")
def splashscreen():
    print("Chapter 12 - working with files, v5.")
# print("Now we add exception handling and error bounds on the year of album release")
def goodby():
    print('\n*** End of Ch12 working with files ***')
def main():
    # Ok, let's load in our inventory from the file
    print("Reading in our inventory")
    our_inventory = read_inventory_from_a_file(INPUT_FILE)
# print_an_inventory(our_inventory)
    print("Writing our report to disk")
# Part 3 - Insert code to open the output file
    # We'd like a text file written to disk that tells us some useful "at a glance" information about our inventory,
    # like obvious mistakes in our data, the number of albums we have in various decades, and the total size of our inventory.
    # Add code below to open the OUTPUT_FILE (specified at the top of this file) for writing.
    # Put some title at the top of your report describing what the report, the current date, and include your name.
    # If you want a starting spot, something like x.write("*** Vintage Vinyl on Wheels ***\n"),
    # followed by x.write(today_timestamp() + "\n") is a beginning, where "x" is the output file handle you've used.
    # See the example ch12_report.txt supplied in the homework. You must contain all the information shown,
    # but you do not have to follow the precise formatting. In other words, include the requested information,
    # but make this look the way you think is pleasing and easy to read.
    # Hint: you will find that a lot of "\n" newlines are needed... the .write() method does not automatically append a
    # newline like print() does, so you have to supply those yourself.
    # your code goes next
    # end of your code
# Part 4 - Continue to write more information into the report file. For Part 4, report on any
    # incorrect values in our inventory, focused on invalid values for year_released.
    # For the purposes of this week's homework, let's assume that year_released is
    # actually correctly stored as an integer, and if the value is 0, then clearly we have a mistake,
    # so, for each album in your inventory that has a year_released of 0, put out a line in your output file and
    # put their title, artist, and year_released along with a few words to show it needs to be fixed.
    # your code goes next
    # end of your code
# Part 5 - Now we need some stats...
    # As our last part, write some information into your file that tells us about our inventory.
    # The information needed:
    # Golden Oldies: any album released between 1948 to 1959, inclusive. I only want to know the quantity.
    # The Rock Era: any album released between 1960 to 1999, inclusive. I only want to know the quantity.
    # The 2000s: any album released from 2000 onward, inclusive. I only want to know the quantity.
    # Finally, we'd like to know the total number of albums in our current inventory
    # your code goes next
    # end of your code
    print("Closing the report file")
    out_file.close() # close the file. Modify this line to match your file handle... I happened to use "out_file"
# end of main
# call main
