Write a program to store water usage data of 4 customers in a text file. The program asks the user to enter account number, customer type (R for residential or B for business), and number of gallons used for each of the 4 customers. Store the data in a text file named "water. txt". Overwrite old data in "water. txt" if the file already exists.

with open ('water. txt','w') as file:

i = 4

while i > 0:

accNo = input ('Enter Account Number: ')

bType = input ('Enter Customer Type R or B: ')

nGallons = input ('Enter Number of gallons: ')

ls = ' '. join (['Account Number:', accNo,'/nType:', bType, '/nNumber Of gallons:', nGallons,'/n/n'])

file. write (ls)

i - = 1

Explanation:

The programming language used is python.

A file water. txt is created, and a counter is initialized to ensure data is collected for all the the customers.

A loop is created to collect the input of the four customers. The data is collected, assigned to a list and joined using the join method, to create a string of the data collected and it is written to the file.

Using a WITH statement allows a file to automatically close.
