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
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.
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.
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.
