'''The functions, named create_ppt_X, are used to create a PowerPoint presentation on a given topic. It utilizes the Wikipedia API and Google Images to gather information and images for the presentation. These functions takes in four parameters: topic, author_main, detail_slide, and theme. The topic parameter is used to scrape data from Wikipedia and gather images from Google Images. The author_main parameter is not used in the current implementation of the function. The detail_slide parameter is used to determine the number of slides to be included in the presentation, with a maximum of 10 slides. The theme parameter is used to set the theme of the presentation, with a default value of "theme_0". The function also contains several helper functions, such as google_images, remove_brackets, and get_data, which are used to scrape data from Wikipedia and gather images from Google Images.'''
