Updated Oct 16, Jupyter Notebook. Updated Aug 20, Python.In this tutorial we will create a fully functional movie database application with Camelot. We assume Camelot is properly installed. If you are not using Spyderyou can skip this and jump to the next section.
In the Project Explorer change the workspace directory, to the directory where you want to put your Camelot Projects. From the command prompt or shellgo to the directory in which the new project should be created. Type the following command:.
A dialog appears where the basic information of the application can be filled in. Select the newly created Videostore directory as the location of the source code.
Press OK to generate the source code of the project. The source code should now appear in the selected directory. To run the application, double click on the main. The application has a customizable menu and toolbar, a left navigation pane, and a central area, where default the Home tab is opened, on which nothing is currently displayed. The navigation pane uses Sections to group Actions. Each button in the navigation pane represents a Sectionand each entry of the navigation tree is an Action.
Most standard Actions open a single table view of an Entity in a new tab.
Notice that the application disables most of the menus and the toolbar buttons. When we open a table view, more options become available. Entities are opened in the active tab, unless they are opened by selecting Open in New Tab from the context menu right click of the entity link, which will obviously open a new tab to right.
Tabs can be closed by clicking the X in the tab itself. Each row is a record with some fields that we can edit others might not be editable. We now see a new window, containing a form view with additional fields. Forms label required fields in bold.
Fill in a first and last name, and close the form. Camelot will automatically validate and echo the changes to the database. We can reopen the form by clicking on the blue folder icon in the first column of each row of the table. Notice also that there is now an entry in our table. Next we will write code for our database model. The Global settings object contains the global configuration for things such as database and file location.
Now we can look at model. Camelot has already imported some classes for us. They are used to create our entities. The aforementioned specifications translate into the following Python code, that we add to our model.GitHub is home to over 40 million developers working together to host and review code, manage projects, and build software together.

How To Build Your First Recommender System Using Python & MovieLens Dataset
The first line in each file contains headers that describe what is in each column. The available datasets are as follows: title. One or more of the following: "alternative", "dvd", "festival", "tv", "video", "working", "original", "imdbDisplay". New values may be added in the future without warning attributes array - Additional terms to describe this alternative title, not enumerated isOriginalTitle boolean — 0: not original title; 1: original title title. Fields include: tconst string - alphanumeric unique identifier of the title directors array of nconsts - director s of the given title writers array of nconsts — writer s of the given title title.
Fields include: tconst string - alphanumeric identifier of episode parentTconst string - alphanumeric identifier of the parent TV Series seasonNumber integer — season number the episode belongs to episodeNumber integer — episode number of the tconst in the TV series title.

In this article, I will show how to use simple Python libraries and built-in capabilities to scrape the web for movie information and store them in a local SQLite database, which can later be queried for data analytics with movie info. Think of this as a project to build your own mini IMDB database! This type of data engineering task — gathering from web and building a database connection — is often the first step in a data analytics project. Before you do any cool predictive modeling, you need to master this step.
This step is often messy and unstructured i. So, you have to extract the data from web, examine its structure and build your code to flawlessly crawl through it. Specifically, this demo will show the usage of following features. Brief descriptions of these are given below. The gateway from Python to web is done through urllib module. It offers a very simple interface, in the form of the urlopen function.
This is capable of fetching URLs using a variety of different protocols. It also offers a slightly more complex interface for handling common situations — like basic authentication, cookies, proxies and so on. These are provided by objects called handlers and openers. Web scraping is often done by API services hosted by external websites. Think of them as repository or remote database which you can query by sending search string from your own little program.
Because it is a free service, they have a restriction of requests per day. Note, you have to register on their website and get your own API key for making request from your Python program. It is easy for humans to read and write. It is easy for machines to parse and generate. These properties make JSON an ideal data-interchange language. The json library can parse JSON pages from strings or files.
It is an extremely useful module and very simple to learn. This module is likely to be used in any Python based web data analytics program as the majority of webpages nowadays use JSON as primary object type while returning data.
This module provides a portable way of using operating system dependent functionality. If you just want to read or write a file see openif you want to manipulate paths, see the os. For creating temporary files and directories see the tempfile module, and for high-level file and directory handling see the shutil module.
In this demo, we will use OS module methods for checking existing directory and manipulate files to save some data. Some applications can use SQLite for internal data storage.
The flow of the program is shown below. Please note that the boiler plate code is available in my Github repository. The basic idea is to send request to external API with a movie title that is entered by the user.
The program then tries to download the data and if successful, prints it out.Recommender systems are no joke. They have found enterprise application a long time ago by helping all the top players in the online market place. Amazon, Netflix, Google and many others have been using the technology to curate content and products for its customers.
Introducing the movie database
Amazon recommends products based on your purchase history, user ratings of the product etc. Netflix recommends movies and TV shows all made possible by highly efficient recommender systems. This article is aimed at all those data science aspirants who are looking forward to learning this cool technology. If you are a data aspirant you must definitely be familiar with the MovieLens dataset.
It is one of the first go-to datasets for building a simple recommender system. Maxwell Harper and Joseph A. The dataset will consist of just overratings applied to over 9, movies by approximately users.
Download the dataset from MovieLens. The data is distributed in four different CSV files which are named as ratings, movies, links and tags.
For building this recommender we will only consider the ratings and the movies datasets. The ratings dataset consists ofobservations and each observation is a record of the ID for the user who rated the movie userIdthe ID of the Movie that is rated movieIdthe rating given by the user for that particular movie rating and the time at which the rating was recorded timestamp.
The movies dataset consists of the ID of the movies movieIdthe corresponding title title and genre of each movie genres. The dataset is a collection of ratings by a number of users for different movies. DataFrame data.
The rating of a movie is proportional to the total number of ratings it has. Therefore, we will also consider the total ratings cast for each movie. The above code will create a table where the rows are userIds and the columns represent the movies. The values of the matrix represent the rating for each movie by each user. Now we need to select a movie to test our recommender system. Choose any movie title from the data.
Here, I chose Toy Story To find the correlation value for the movie with all other movies in the data we will pass all the ratings of the picked movie to the corrwith method of the Pandas Dataframe.
The method computes the pairwise correlation between rows or columns of a DataFrame with rows or columns of Series or DataFrame. Now we will remove all the empty values and merge the total ratings to the correlation table. We can see that the top recommendations are pretty good. Contact: amal.
