Here's a theoretical breakdown of how to create a login form in Python:
Define the login function: Start by defining a function called login() that will handle the login process.
Prompt for username and password: Within the login() function, use the input() function to prompt the user to enter their username and password.
Check username and password: Compare the entered username and password with the correct credentials stored in the program. For simplicity, you can hardcode the correct username and password within the program.
Validate credentials: Check if the entered username and password match the correct credentials. If they match, print a success message. If they don't match, print an error message and allow the user to try again.
Run the login function: At the end of the script, call the login() function to start the login process when the program is executed.
Here's a step-by-step breakdown of the login form creation process:
Step 1: Define the login() function:
python
Copy code
def login():
Code for login process will go here
Step 2: Prompt for username and password:
python
Copy code
username = input("Enter your username: ")
password = input("Enter your password: ")
Step 3: Check username and password:
python
Copy code
if username == "admin" and password == "password":
print("Login successful!")
else:
print("Invalid username or password. Please try again.")
Step 4: Run the login function:
python
Copy code
if _name_ == "__main__":
login()
This simple login form can be enhanced in various ways, such as adding error handling for invalid input, encrypting passwords for security, or integrating with a database for user authentication.
