Trying to read a file - python

Question

I am trying to write a code (on python) that will read a file with a list of products, a GTIN-8 code for each, a description, stock and price for each individual product.

So far I managed to read the top line, printing out its details, but I am unsure how to read the next line down. Any Help? Please try and keep it simple :)

Code for my man Doroskevic:

#csv is imported to read/write to the file
import csv

#Each Product is printed alongside it's GTIN-8 code and Price
print("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~")
print("~ Welcome to Toms bits and bobs ~")
print("Pencil,          12346554, £0.40")
print("50 Staples,      12346882, £1.00")
print("50 Paper Clips,  12346875, £1.20")
print("Large Eraser,    12346844, £1.50")
print("100 A4 Sheets,   12346868, £2.00")
print("100 A3 Sheets,   12346837, £2.50")
print("25 Byro Pens,    12346820, £2.20")
print("Handwriting Pen, 12346899, £5.50")
print("50 Split Pins,   12346813, £0.60")
print("Office Chair,    12346912, £25.00")
print("~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~")

#The file is opened and the user inputs the code for the product they
#wish to find.
file = open("Product_list.csv", "r")
purchase = input(print("Please enter the GTIN-8 code of the product you wish to purchase e.g 12346554"))
line = file.readline()
data = line.split(",")
if purchase == "12346554":
    while(line):
        print ("Product: ", data[0])
        print ("GTIN-8 code: ", data[1])
        print ("Stock: ", data[2])
        print ("Description: ", data[3])
        print ("Price: ", data[4])
        line = file.readline()
        break
if purchase == "12346882":
    while(line):
        print ("Product: ", data[0])
        print ("GTIN-8 code: ", data[1])
        print ("Stock: ", data[2])
        print ("Description: ", data[3])
        print ("Price: ", data[4])
        line = file.readline()
        break

file.close()

hi, could you show your code? – e.doroskevic Feb 09 '16 at 11:37 — e.doroskevic, Feb 09 '16 at 11:37

Example:

path = 'c:/users/-e/my documents/text.txt'

with open(path, 'r') as file:
    data = file.readlines()

    for line in data:
        print(line, end='')

Output:

Are all the good times dead and gone?
Come and go and come and go (come and come and go)

But some are just black holes

Function .readlines() will read all lines within file into a list structure. This will allow further operations to be carried out as needed.

@AdrianHHH that's cool, where does it state that people should be down-voted for providing answers to duplicate questions? I think this should be taken into a chat for a broader discussion – e.doroskevic Feb 09 '16 at 12:13
