  1. If the search term returns multiple pages with similar or related content, the Wikipedia module may raise a DisambiguationError exception. In this case, you can catch the exception and use the options provided in the exception to determine which page to retrieve.
  2.  
  3. Here's an example of how you can catch the DisambiguationError exception and select the best page from the options:
  4.  
  5.  
  6. import wikipedia
  7.  
  8. try:
  9.    # Search for pages that match the search term
  10.    results = wikipedia.search("search term")
  11.  
  12.    # Get the best page from the search results
  13.    page = wikipedia.page(results[0])
  14.  
  15. except wikipedia.DisambiguationError as e:
  16.    # Print the options provided in the exception
  17.    print("Multiple pages were found with the search term:")
  18.    print(e.options)
  19.  
  20.    # Prompt the user to select the best page
  21.    selection = input("Please select the best page: ")
  22.  
  23.    # Get the page for the selected option
  24.    page = wikipedia.page(selection)
  25.  
  26. # Print the page's title and summary
  27. print(page.title)
  28. print(page.summary)
  29.  
  30.  
  31.  
  32. This code will search for pages that match the search term, and if multiple pages are found, it will catch the DisambiguationError exception and print the options provided in the exception. The user can then select the best page from the options, and the code will retrieve the selected page and print its title and summary.
  33.  
  34. You can also use the options provided in the DisambiguationError exception to automatically select the best page, rather than prompting the user to make a selection. For example, you could use a simple heuristic to select the page with the shortest title or the page with the most related terms to the search term.
