AirBnB is an online platform or marketplace that allows people to list, discover, and book accommodations around the world, ranging from private rooms to entire houses or apartments.
This project attempts to clone the popular AirBnB - to mimic the core functionality and features of the Web Application, providing a similar user experience.
The focus of this project is to interact with the mimic AirBnb via the Console - the command line interface.
since the interaction with the AirBnB project will be from the console, there is a need to create commands that will handle various operations.
A command interpreter is a program that interprets and executes commands entered by users in a text-based interface. it will provide a way to interact with the mimic AirBnb via the console.
In Python, the cmd module provides a framework for building command-line interpreters or shells. It allows you to create interactive command-line applications with custom commands and functionalities.
To use the cmd module, you need to import it in your Python script:
import cmd
-> You can then create a subclass of the cmd.Cmd class and define your own commands by overriding the appropriate methods. Here's a simple example:
class MyCmd(cmd.Cmd):
prompt = '(AirBnB) ' # display prompt to user
do_greet(self, line):
""" welcomes the user
Args:
line : The name of the user
"""
print("Welcome, {}".format(line))
do_EOF(self):
""" Exit the command interpreter"""
return True
if name == 'main': MyCmd().cmdloop()
-> In the above example we created a subclass of cmd.Cmd called MyCmd, we define two commands called, "greet" and "EOF". The 'do' prefix is necessary to define the command method.
-> To start the interpreter will need to run it in a loop - the cmdloop().
-> When the script runs, you will see the command prompt "(AirBnB) ". you can enter a command like "greet Olalekan and Idris" to the command line to greet the user with "Welcome, Olalekan and Idris. Also, a command like "EOF" or CTRL + D to exit the interpreter successfully.
-> The cmd module provides other methods and attributes that you can override to customize the behavior of your command-line interpreter
