How to verify username and password from CSV file in Python?

2024/7/8 4:52:45

I am doing a Python project where I have to verify my username and password from a csv file where the first two rows and columns have the username and password as 'hi'.

Current Code:

    answer = input("Do you have an account?(yes or no) ")
if answer == 'yes' :login = Falsecsvfile = open("Username password.csv","r")reader = csv.reader('Username password.csv')username = input("Player One Username: ")password = input("Player One Password: ")for row in reader:if row[0]== username and row[1] == password:login = Trueelse:login = Falseif login == False:print("Incorrect. Game Over.")exit()else:print("You are now logged in!")
else:print('Only Valid Usernames can play. Game Over.')exit()

Answer

Here is what you want

First you had wrong login logic I changed the file name for my convinience

import csvlogin = False
answer = input("Do you have an account?(yes or no) ")if answer == 'yes' :with open('upassword.csv', 'r') as csvfile:csv_reader = csv.reader(csvfile)username = input("Player One Username: ")password = input("Player One Password: ")for row in csv_reader:print(row[0], row[1])print(username, password)if row[0]== username and row[1] == password:login = Truebreakelse:login = Falsebreakif login == True:print("You are now logged in!")else:print("Incorrect. Game Over.")exit()    
else:print('Only Valid Usernames can play. Game Over.')exit()

I have also some print statements to help you understand the workflow

And try to avoid opening files like this

csvfile = open("Username password.csv","r")
