Final answer:
To remove duplicate entries in a department library's book collection, you can write a Python function that uses a set to filter out duplicates and returns a list of unique books.
Step-by-step explanation:
Python Program to Remove Duplicate Entries in a Department Library
To create a Python program for a department library that removes duplicate entries from a list of n books, you can use a function that filters duplicates out of the list. One approach is to use a set to store unique book entries, as sets automatically disregard duplicate items. See the following example code which includes a function to remove duplicates:
def delete_duplicates(books):
# Convert list to a set to remove duplicates, and then back to a list
unique_books = list(set(books))
return unique_books
# Example usage:
book_list = ['Book A', 'Book B', 'Book A', 'Book C']
unique_book_list = delete_duplicates(book_list)
print(unique_book_list)
This Python program will output the book list without duplicates, preserving only unique entries:
['Book A', 'Book B', 'Book C']
