User_Sign-Up_and_Login_Form_created_with_Python

Used Python to build a sign-up and login form for users

Started by creating a text file named Credentials.txt that contain a dictionary of user Credentials, usernames and passwords.

Next, I built the login function.

• Needed to take 2 inputs, name and password
• Ask the user to enter their username and password
• Search if the username already already existed in the Credentials.txt file
  • If the username was found in the file, then check if the entered password was correct for this user and then return a welcome statement for the user
  • If the username was found in the file, but the password entered was not correct for the user:
    • The user is prompted to reenter the password until they enter the correct answer
    • Then a welcome statement is returned
  • If the username was not found in the file:
    • Display the statement "Username does not exist. Please create an account"

Then I design the sign up function.

• Needed to take 2 inputs, newName and newPassword
• Ask the user to input their username
• Check to see if the username already exists in the Credentials.txt file
  • If the username already exists:
    • The user is prompted to enter a new username to use instead until an original username is entered
  • If the username enetered is original:
    • The user is prompted to create a password for their account
    • Then the username and password are appended into the Credentials.txt file
    • Display the statement "Account created successfully" once appropriate credentials have been entered

Lastly, I set up the main program.

• Started by having a prompt for the user to enter either 1 to Login, 2 to Create an Account, or 3 to Exit
• If the user enters 1:
  • the login function runs and the user is prompted to enter their username and password
    • If the username is not found in the Credentials.txt file, then the user is asked to create an account using the sign up function
• If the user enters 2:
  • the sign up function is run and a new account is created
• If the user enters 3:
  • The form is exitted and no action is preformed
• If the user enters anything other than 1, 2, or 3:
  • An Invalid Input statement is displayed and the user is prompted to enter a valid input
