The most common answer is:

num_of_categories = 3
num_of_question = 3

# Loop for each category
for i in range(num_of_categories):
    category_name = input("Enter a category: ")
    entries = []  # Initialize an empty list to store entries for each category

    # Loop for each question within a category
    for j in range(num_of_question):
        entry = input(f"Enter something in the category '{category_name}': ")
        entries.append(entry)  # Append each entry to the list

    # Print the category and its entries
    print(category_name + ": " + " ".join(entries))

This code will:

• Prompt the user to enter a category name for a predetermined number of categories (num_of_categories).
• For each category, it will then ask the user to enter items (num_of_question times) that belong to that category.
• After collecting the items for a category, it prints the category name followed by the items separated by spaces.

This approach uses a list (entries) to collect items for each category, simplifying the process of adding and displaying items. The join() method is used to concatenate all items in the list into a single string with spaces in between for printing.
