answer:Here's the Python function to compare the sales performance of two product lines:```pythondef compare_sales_performance(sales_product_a, sales_product_b): total_sales_a = sum(sales_product_a) total_sales_b = sum(sales_product_b) if total_sales_a > total_sales_b: return "Product A" elif total_sales_b > total_sales_a: return "Product B" else: return "Tie"```This function takes two lists of integers, `sales_product_a` and `sales_product_b`, representing the monthly sales figures for Product Line A and Product Line B, respectively.It calculates the total sales for each product line by summing up the corresponding list using the `sum()` function.Then, it compares the total sales of the two product lines:- If the total sales of Product Line A (`total_sales_a`) are higher than those of Product Line B (`total_sales_b`), it returns the string `"Product A"`.- If the total sales of Product Line B are higher than those of Product Line A, it returns the string `"Product B"`.- If the total sales of both product lines are equal, it returns the string `"Tie"`.

answer:Here's the Python function to identify blues-influenced songs from a list of song titles:```pythondef identify_blues_influenced_songs(song_titles): blues_keywords = ["blues", "blue", "mojo", "delta", "crossroad"] blues_influenced_songs = [] for song in song_titles: song_lower = song.lower() for keyword in blues_keywords: if keyword in song_lower: blues_influenced_songs.append(song) break return blues_influenced_songs```This function takes a list of song titles as input and returns a list of song titles that contain keywords commonly associated with blues music. Here's how it works:1. The function defines a list `blues_keywords` containing the keywords to look for: "blues", "blue", "mojo", "delta", and "crossroad".2. An empty list `blues_influenced_songs` is initialized to store the songs that contain any of the keywords.3. The function iterates over each song title in the input list `song_titles`.4. For each song title, it converts the title to lowercase using the `lower()` method to make the search case-insensitive.5. The function then iterates over each keyword in the `blues_keywords` list.6. If the keyword is found in the lowercase version of the song title, the original song title is appended to the `blues_influenced_songs` list, and the inner loop breaks to move on to the next song title.7. After iterating over all song titles, the function returns the `blues_influenced_songs` list containing the song titles influenced by blues music.Note that the `break` statement inside the inner loop is used to avoid adding the same song title multiple times if it contains more than one keyword.

answer:Here's the Python function to calculate the total duration of a playlist based on a list of song durations:```pythondef calculate_playlist_duration(playlist_durations): total_seconds = 0 for duration in playlist_durations: minutes, seconds = map(int, duration.split(":")) total_seconds += minutes * 60 + seconds total_minutes = total_seconds // 60 remaining_seconds = total_seconds % 60 return f"{total_minutes:02d}:{remaining_seconds:02d}"```Explanation:1. The function `calculate_playlist_duration` takes a list of strings `playlist_durations` as input, where each string represents the duration of a song in the format "MM:SS".2. We initialize `total_seconds` to 0, which will store the total duration of the playlist in seconds.3. We loop through each duration string in `playlist_durations`: - We split the duration string into minutes and seconds using the `split(":")` method and convert them to integers using the `map(int, ...)` function. - We calculate the total seconds for the current song by multiplying the minutes by 60 and adding the seconds. - We add the total seconds for the current song to `total_seconds`.4. After the loop, we have the total duration of the playlist in seconds stored in `total_seconds`.5. We calculate the total minutes by performing integer division `total_seconds // 60`.6. We calculate the remaining seconds by taking the modulus `total_seconds % 60`.7. We format the total minutes and remaining seconds into the desired "MM:SS" format using an f-string with string formatting specifiers `{total_minutes:02d}` and `{remaining_seconds:02d}`. The `:02d` ensures that the numbers are padded with leading zeros if necessary.8. Finally, we return the formatted string representing the total duration of the playlist.
