In this segment of the video, the presenter demonstrates using an app to filter data by year, building an app with three screens, and incorporating programming constructs like variables, functions, conditionals, lists, and loops. The requirements for a hackathon project include easy-to-navigate screens, meaningful use of data sets, and various programming elements like mapping, filtering, and reduction of lists. The presenter sets up the first screen as a welcome screen with an image, label, and button, and designs an input screen for user interaction including filtering by year. The presenter explains concepts like mapping, filtering, and reducing lists in the context of building the app.

In this segment of the video, the creator demonstrates filtering Netflix shows by decade and year. They set up filtering options by year using drop-down menus and create buttons for search and restarting. They also prepare a screen for displaying search results, including a text area. The creator then discusses organizing data into a list, declaring variables for movie titles and release years.
00:10:00
In this segment of the video, the speaker discusses setting up variables and on-event actions in a project. They mention the creation of variables like “input year” and “name titles list,” preparing for user interactions such as clicking the start or search buttons. The speaker demonstrates connecting user actions to specific screens within the project using on-click events. Additionally, they emphasize the importance of updating variables, such as “input year,” based on user input before proceeding to the next screen. The segment concludes with the speaker setting up a function called “search” for handling data related to the user-selected year.
00:15:00
In this segment of the video, the presenter discusses searching, filtering, and looping through a list of data. They explain using a for loop to iterate through the list and access elements by index (starting from 0). The for loop is used to go through each item in the list, with a demonstration of how the loop works. The concept of the length property of a list to iterate through the entire list is introduced as a way to ensure that the loop goes through all the items in the list.
00:20:00
In this segment of the video, the speaker is demonstrating how to search through a list of movie titles based on the release year input by the user. They use a filter to compare the input year with each film’s release year in the list. If the release year matches the input year, the corresponding title is added to the output list. The speaker ensures to reset the output list before each search to avoid duplicate entries. The demonstration successfully filters and adds titles based on the input year, as shown in the output.
00:25:00
In this segment of the video, the speaker discusses converting data into a list and creating a function to print out the results. They explain the importance of handling varying data lengths to avoid errors. The process involves iterating over the list, building a string of results, and formatting it properly, including handling potential new lines. The speaker works through debugging errors and ensuring consistency in variable names. They highlight meeting project requirements, such as utilizing multiple programming concepts like loops, functions, and conditionals. The importance of adding comments to functions is also emphasized. The speaker mentions the potential for further app development and customization, encouraging viewers to tailor the code to reflect their own preferences.
00:30:00
In this segment of the video, the speaker discusses making the code reflect personal style and individuality. They demonstrate looping through a list, converting to a string, and outputting it on the screen. Additionally, they explain a function that filters a titles list based on the year and adds matching titles to another list. The speaker encourages viewers to personalize the design, mentioning the flexibility to work with various datasets and data types beyond dates, such as heights or numbers. They emphasize making the project unique and suggest adding an image to enhance the presentation.
