question:Write a python function to calculate the average age of individuals in a list of dictionaries, where each dictionary contains information about a person, including their age. The input to the function should be a list of dictionaries, each with the key "age" holding an integer value. The function should return the average age as a float.Input:- A list of dictionaries, e.g., `[{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}, {"name": "Charlie", "age": 35}]`Expected Output:- A float representing the average age of the individuals in the list.Example:- For the input `[{"name": "Alice", "age": 30}, {"name": "Bob", "age": 25}, {"name": "Charlie", "age": 35}]`, the expected output should be `30.0`.

answer:def calculate_average_age(people): total_age = 0 num_people = len(people) for person in people: total_age += person["age"] if num_people > 0: average_age = total_age / num_people return average_age else: return 0.0

question:Write a python function to calculate the total time spent in a yoga session, given a list of tuples where each tuple represents an activity with its start and end time. Each time is in the format "HH:MM". The function should take this list of tuples as input and return the total time spent as a string in the format "H hours, M minutes".Input: A list of tuples, where each tuple contains two strings representing the start and end times of an activity during the yoga session. The times are in "HH:MM" format and in 24-hour time.Output: A string representing the total time in the format "H hours, M minutes".Example:```pythonactivities = [("09:00", "09:30"), ("10:00", "10:45"), ("11:15", "12:00")]# The total time spent would be (30 + 45 + 45) minutes = 2 hours, 0 minutes# Expected output: "2 hours, 0 minutes"```

answer:Here's the Python function to calculate the total time spent in a yoga session:```pythondef calculate_total_time(activities): total_minutes = 0 for start_time, end_time in activities: start_hour, start_minute = map(int, start_time.split(":")) end_hour, end_minute = map(int, end_time.split(":")) start_minutes = start_hour * 60 + start_minute end_minutes = end_hour * 60 + end_minute total_minutes += end_minutes - start_minutes total_hours = total_minutes // 60 total_minutes %= 60 return f"{total_hours} hours, {total_minutes} minutes"```This function takes a list of tuples `activities` as input, where each tuple represents the start and end time of an activity in the format "HH:MM". It calculates the total time spent in minutes by iterating over each activity, converting the start and end times to minutes, and adding the difference to the `total_minutes` variable. Finally, it converts the total minutes to hours and minutes and returns a formatted string with the result.

question:Write a python function to take a list of Japanese sentences (strings) and return a list of English sentences (strings) by translating each sentence using a given dictionary. The translation dictionary maps Japanese words (keys) to their corresponding English words (values). The function should replace each word in the sentence according to the dictionary and keep the sentence structure intact.Input:- A list of Japanese sentences (e.g., `["私は猫が好きです", "彼は犬を飼っています"]`)- A dictionary for translation (e.g., `{"私は": "I", "猫": "cat", "が": "like", "好きです": "", "彼は": "He", "犬": "dog", "を": "", "飼っています": "owns"}`)Output:- A list of translated English sentences (e.g., `["I like cat", "He owns dog"]`)Note:- If a word in the sentence does not exist in the dictionary, leave it unchanged.- Assume that the input sentences contain only words separated by spaces and punctuation marks should be ignored.Example:```pythonjapanese_sentences = ["私は猫が好きです", "彼は犬を飼っています"]translation_dict = {"私は": "I", "猫": "cat", "が": "like", "好きです": "", "彼は": "He", "犬": "dog", "を": "", "飼っています": "owns"}# Example output: ["I like cat", "He owns dog"]```

answer:def translate_sentences(japanese_sentences, translation_dict): english_sentences = [] for sentence in japanese_sentences: words = sentence.split() translated_words = [] for word in words: translated_word = translation_dict.get(word, word) translated_words.append(translated_word) translated_sentence = " ".join(translated_words) english_sentences.append(translated_sentence) return english_sentences

question:Write a python function to analyze the monthly stock price data of a retail company and identify months with significant price increases. The function should take a list of dictionaries as input, where each dictionary contains 'month' (a string representing the month, e.g., "January"), 'open' (the opening stock price for the month), and 'close' (the closing stock price for the month). The function should return a list of strings representing the months where the stock price increased by at least 10% from the opening to the closing price.Example:Input:```python[ {'month': 'January', 'open': 100, 'close': 110}, {'month': 'February', 'open': 110, 'close': 105}, {'month': 'March', 'open': 105, 'close': 120}]```Expected Output:```python['January', 'March']```

answer:def analyze_stock_prices(stock_data): significant_increases = [] for data in stock_data: month = data['month'] open_price = data['open'] close_price = data['close'] price_change = (close_price - open_price) / open_price * 100 if price_change >= 10: significant_increases.append(month) return significant_increases

question:Write a python function to analyze a list of news article sentiments related to conflict and determine the overall emotional impact on civilians. The function should take a list of strings as input, where each string represents the sentiment of a news article (such as "positive", "negative", or "neutral"). The function should return a dictionary indicating the count of each sentiment type and the predominant sentiment across all articles. For example, given the input `["positive", "negative", "neutral", "negative", "positive", "negative"]`, the expected output would be a dictionary like `{"positive": 2, "negative": 3, "neutral": 1, "predominant_sentiment": "negative"}`. If there is a tie for the predominant sentiment, the function should return any one of the tied sentiments as the predominant sentiment.

answer:def analyze_news_sentiments(article_sentiments): sentiment_counts = {"positive": 0, "negative": 0, "neutral": 0} for sentiment in article_sentiments: sentiment_counts[sentiment] += 1 max_count = max(sentiment_counts.values()) predominant_sentiment = [sentiment for sentiment, count in sentiment_counts.items() if count == max_count][0] sentiment_counts["predominant_sentiment"] = predominant_sentiment return sentiment_counts

question:Write a python function to help me organize the musical pieces in our ensemble's repertoire. Each piece is represented as a dictionary containing the fields: 'title', 'composer', 'year', and 'duration' (in minutes). I would like to sort the pieces based on their year of composition in ascending order. If two pieces were composed in the same year, they should be further sorted by their title in alphabetical order. The function should take a list of such dictionaries as input and return a new list of dictionaries sorted according to the rules mentioned above.Input: A list of dictionaries, each representing a musical piece with the fields 'title', 'composer', 'year', and 'duration'.Output: A new list of dictionaries sorted by 'year' and then by 'title'.Example:```pythonpieces = [ {"title": "Concerto in A", "composer": "Composer A", "year": 1750, "duration": 15}, {"title": "Sonata in C", "composer": "Composer B", "year": 1720, "duration": 12}, {"title": "Allegretto", "composer": "Composer C", "year": 1750, "duration": 10}, {"title": "Serenade", "composer": "Composer D", "year": 1740, "duration": 8}]sorted_pieces = sort_pieces(pieces)print(sorted_pieces)```Expected Output:```python[ {"title": "Sonata in C", "composer": "Composer B", "year": 1720, "duration": 12}, {"title": "Serenade", "composer": "Composer D", "year": 1740, "duration": 8}, {"title": "Allegretto", "composer": "Composer C", "year": 1750, "duration": 10}, {"title": "Concerto in A", "composer": "Composer A", "year": 1750, "duration": 15}]```

answer:Here's the Python function to sort the list of dictionaries representing musical pieces based on the given criteria:```pythondef sort_pieces(pieces): return sorted(pieces, key=lambda x: (x['year'], x['title']))```This function uses the `sorted` built-in function to sort the list `pieces`. The `key` parameter is used to specify the sorting criteria. In this case, we use a lambda function `lambda x: (x['year'], x['title'])` as the key.The lambda function takes each dictionary `x` from the list and returns a tuple `(x['year'], x['title'])`. The `sorted` function will first sort the list based on the `'year'` values in ascending order. If two dictionaries have the same `'year'` value, they will be further sorted based on their `'title'` values in alphabetical order.The sorted list of dictionaries is then returned by the function.
