Registration System in Python

A registration system is essential for securely managing user data across various platforms, from websites to event management. This project guides you through building a registration system in Python, complete with features like email validation, password encryption, and data storage. By creating this system, you’ll gain hands-on experience with user input handling, file operations, and security measures, making it a valuable project for both beginners and intermediate Python developers.

Build a Registration System in Python

A registration system helps in managing users by allowing them to sign up and store their details securely. It involves handling various components such as:

• User Input: Collecting data like name, email, and password from users.
• Data Validation: Ensuring that the data entered is in the correct format (e.g., email validation, password checks).
• Data Storage: Storing the user data in a file or database.

This project is ideal for beginners as it touches on key programming concepts, including input handling, file I/O operations, and error checking.

Step 1: Setting Up the Basic Structure

Let’s start by setting up a simple console-based registration system in Python. Our system will prompt users to enter details like name, email, and password, and store them in a file for later retrieval.

Here’s a basic structure for our registration system:

#---Import Librarires
from tkinter import *
from tkinter import ttk
from tkinter import messagebox

#----Functions/Actions

def validation():
    if name.get()!="" and email.get()!="" and password.get()!="" and gender.get()!="" and age.get()!="":
        email_check=email_validation()
        password_check=password_validataion()
        duplicate_check=duplicates()
        if email_check:
            if duplicate_check:
                messagebox.showinfo("information","User Email Already Exist")
            elif password_check:
                insertion_data()
                messagebox.showinfo("information","Data Inserted Sucessfully")
                shifting_form()
            else:
                messagebox.showerror("Error","Password should be (max 7 characters ,upper and lower case letter , number and symbol)")
        else:
            messagebox.showerror("Error","Email Fromat Is Not invalid")
    else:
        messagebox.showerror("Error","Fill All The Required Feilds")

Step 2: Explanation of the Code

1. Email Validation:

• The validate_email() function uses a regular expression to check if the email entered by the user follows a valid format.
• If the email is not valid, the program prompts the user to try again.

1. User Registration:

• The register_user() function collects user input for the name, email, password, and password confirmation.
• If the passwords don’t match or the email is invalid, appropriate error messages are displayed, and the registration is aborted.

1. Data Storage:

• If the input passes all validation checks, the user’s data is stored in a file (users.txt). Each line in the file contains a user’s name, email, and password, separated by commas.
• Using a file allows you to maintain a persistent storage of registered users that can be used for further processing.

Step 5: Running the Application

To run the registration system:

1. Save the code in a Python file (e.g., signup.py.).
2. Run the file from the terminal or command prompt:

   python registration_system.py
