This is a simple inventory management system written in Python using Flask.

• Python 3.x
• Flask

1. Clone the repository.

2. Navigate to the project directory.

3. Create a virtual environment and activate it:

   pip install virtualenv
   virtualenv venv

   • Windows:

     venv\Scripts\activate

     For Windows, if this is your first time running the script, you might get an error like below:

     venv\Scripts\activate : File C:\flask_project\venv\Scripts\Activate.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170.
     At line:1 char:1
     + venv\Scripts\activate
        + FullyQualifiedErrorId : UnauthorizedAccess

     This means that you don’t have access to execute the scripts.

     To solve this error, run PowerShell as admin. When you right-click on the PowerShell icon, choose the option ‘Run as administrator’. Now, PowerShell will open in admin mode.

     Type the following command in Shell:

     set-executionpolicy remotesigned

   • Linux:

     source ./venv/bin/activate

4. Install the requirements:

   pip install flask
   pip install db-sqlite3

5. Run the application:

   flask --app main run

• Add Item: POST /items
• View Items: GET /items
• Update Item: PUT /items/<id>
