Store SQL query as a variable with a CGI Python script












0















I'm a newbie to python and cgi.



How do I store an SQL query as a python variable in a cgi script?



Currently, my script is:



#!/usr/bin/python3
#enable debugging - BEGIN
import cgi
import cgitb
cgitb.enable()
#enable debugging - END
#HTTP Headers - BEGIN
#set encoding to UTF-8
print("Content-Type: text/html;charset=utf-8")
print()
#HTTP Headers - END
#HTML Content - BEGIN
print("<h1>Form Test</h1>")
data = cgi.FieldStorage()
username = data['username'].value
print("<p><b>Hello, " + username + "</b></p>")

import sqlite3
conn = sqlite3.connect('/home/user/BankingApp.db')
c = conn.cursor()
#Display SUM of Balances:
print ("<h1>Bank's Total Balance</h1><br />")
for row in c.execute('SELECT SUM(Balance) FROM Accounts')
print ("Bank's Balance: $")
print (row)


It produces the output:




Bank's Balance: $ (10000.0,)




I want to print out the SUM without the parenthesis so that it reads like:




Bank's Balance: $ 10000.0




I figure if I can store the SUM query into a variable, I can format the output however I want.



Thank you.
