==============================

## Import module for handling csv files.
import csv
## You are not allowed to import any other module into this file.

## display_playlist( filename )
## Replace the following dummy function with one that reads the playlist
## from the csv file corresponding to the filename argument and prints
## out the playlist in the format shown in the coursework specification
## document.
##

## Note: Check whether the filename argument ends in ".csv". If it doesn't
## then you should add ".csv" to get the actual name of the CSV file that
## will be opened.

def display_playlist( filename ):
   if not filename.endswith('.csv'):
       filename = filename + ".csv"
  
   print( '\n Running display_playlist( "{}" )'.format(filename) )
   data = get_datalist_from_csv(filename)
   line = '-' * 113;
   print(line)
   print('|', pad_to_length(data[0][0], 40), '|', pad_to_length(data[0][1], 25), '|', pad_to_length(data[0][2], 30), '|', pad_to_length(data[0][3], 5), '|')
   print(line)
   for i in range(1, len(data)):
       print('|', pad_to_length(data[i][0], 40), '|', pad_to_length(data[i][1], 25), '|', pad_to_length(data[i][2], 30), '|', pad_to_length(data[i][3], 5), '|')
   print(line)
  
## You can use the following function to read data from a csv format file
def get_datalist_from_csv( filename ):
   ## Create a 'file object' f, for accessing the file:
   with open( filename ) as f:
       reader = csv.reader(f) # create a 'csv reader' from the file object
       datalist = list( reader ) # create a list from the reader
   return datalist

## The following function may be useful for aligning your table columns
## It adds spaces to the end of a string to make it up to length n.
def pad_to_length( string, n):
   return string + " "* (n-len(string)) ## s*n gives empty string for n<1

## Run the display_playlist function on the example files
## (The ".csv" should get added by display_playlist)
display_playlist( "geek-music.csv" )
display_playlist( "snake-music")
