Can Anyone help my code is not working

Using the file: "Purchases.csv".

Write a program that will provide the following information (displayed on the screen):

1) The total number of purchase orders.

2) The average purchase showing three decimals.

3) The Number of Purchases over 1,800.

4) The average amount of Purchases over 1,800 showing three decimals.

Present you output in some Tabular format. Something similar to:

Total Number of Purchases: xxxx

Amount of Average Purchase: xxxx.xxx

Number of Purchase Orders over $1,800: xxxx

Amount of Average Purchase over $1,800: xxxx.xxx

import csv

data = []

purchases = csv.reader(open('Purchases.csv', 'rb'))

for value in purchases: data.append(float(value[0]))

total_purchase = len(data) print("Total Number of Purchase: {}".format(total_purchase)) print("Amount of Average Purchase: {:.3f}".format(sum(data)/total_purchase))

purchase_over_1800 = sum(1 for i in data if i>1800) print("Number of Purchase Orders over $1,800: {}".format(purchase_over_1800)) print("Amount of Average Purchase over $1,800: {:.3f}".format(sum([i for i in data if i>1800])/purchase_over_1800))
