question:Write a python function to convert a given list of strings into a single string, where each original string is separated by a hyphen ("-"). The function should take a list of strings as input and return the resulting single string. For example, if the input list is `["Jaido", "P", "is", "the", "best"]`, the function should return the string `"Jaido-P-is-the-best"`. The function should handle edge cases such as an empty list, which should return an empty string. Input: A list of strings.Output: A single string with each element from the list separated by a hyphen. Example:```python# Example inputstrings_list = ["Jaido", "P", "rocks"]# Expected output# "Jaido-P-rocks"```
answer:Here's the Python function to convert a list of strings into a single string separated by hyphens:```pythondef convert_to_hyphenated_string(string_list): if not string_list: return "" else: return "-".join(string_list)```This function takes a list of strings as input and returns a single string with each element from the list separated by a hyphen. Here's how it works:1. The function first checks if the input `string_list` is empty using the condition `if not string_list`. If the list is empty, it returns an empty string `""`.2. If the list is not empty, the function uses the `join()` method with the separator `-` to concatenate all the strings in the list. The `join()` method takes an iterable (in this case, the list `string_list`) and returns a string by joining all the items in the iterable with the specified separator (here, `-`).3. The final hyphenated string is returned by the function.For example, if you call the function with the input `["Jaido", "P", "rocks"]`, it will return the string `"Jaido-P-rocks"`. If you call it with an empty list `[]`, it will return an empty string `""`.
question:Write a python function to analyze a text document and count the occurrences of each word, ignoring punctuation and case sensitivity. The input is a string representing the text, and the output should be a dictionary where the keys are words and the values are the number of times each word appears in the text.For the purpose of this function, words are defined as sequences of characters separated by spaces, and punctuation marks should not be considered part of the words. You can assume that the input text will only contain letters, spaces, and basic punctuation marks like periods, commas, exclamation points, and question marks.Example:Input:```"Hello, world! Welcome to the world of programming. Isn't programming fun?"```Expected Output:```python{ 'hello': 1, 'world': 2, 'welcome': 1, 'to': 1, 'the': 1, 'of': 1, 'programming': 2, 'isn': 1, 't': 1, 'fun': 1}```Note: In the example above, "isn't" is split into "isn" and "t" after removing the punctuation.
answer:def analyze_text(text): import string # Convert the text to lowercase and remove punctuation text = text.lower().translate(str.maketrans('', '', string.punctuation)) # Split the text into words words = text.split() # Create a dictionary to store word counts word_counts = {} # Count the occurrences of each word for word in words: word_counts[word] = word_counts.get(word, 0) + 1 return word_counts
question:Write a Python function to reverse the words in a given sentence without changing the order of the words themselves. The input will be a string containing a sentence, and the output should be a string where each word in the sentence is reversed, but their order remains the same.For example, given the input string `"Hello world, this is a test!"`, the expected output should be `"olleH ,dlrow siht si a !tset"`.Please ensure that the function handles punctuation and spaces appropriately, maintaining them in their respective positions in the sentence.
answer:def reverse_words_in_sentence(sentence): words = sentence.split() reversed_words = [] for word in words: reversed_word = word[::-1] reversed_words.append(reversed_word) reversed_sentence = ' '.join(reversed_words) return reversed_sentence
question:Write a python function to calculate the total cost of manufacturing a batch of gadgets based on the cost of raw materials, labor, and a predetermined markup percentage for profit. The function should take three arguments: `raw_material_cost` (a float representing the cost of materials in dollars), `labor_cost` (a float representing the cost of labor in dollars), and `markup_percentage` (an integer representing the percentage markup for profit).The function should return the total cost as a float, which includes the sum of raw materials and labor costs plus the markup percentage applied to this sum.Input:- `raw_material_cost`: float- `labor_cost`: float- `markup_percentage`: intOutput:- A float representing the total cost.Example:```pythoncalculate_total_cost(100.0, 150.0, 20)```This should return `300.0` because the total cost without markup is `250.0` (100 + 150) and the markup is `50.0` (20% of 250), making the total cost `300.0`.
answer:def calculate_total_cost(raw_material_cost, labor_cost, markup_percentage): base_cost = raw_material_cost + labor_cost markup_amount = base_cost * (markup_percentage / 100) total_cost = base_cost + markup_amount return total_cost
question:Write a python function to calculate the average number of goals scored per match, given a list of dictionaries where each dictionary represents a match. Each dictionary contains the keys `'goals_scored'` and `'minutes_played'`. The function should only consider matches where the player played at least 45 minutes. Input:- A list of dictionaries, where each dictionary has the following structure: ```python { 'goals_scored': int, # The number of goals scored in the match 'minutes_played': int # The number of minutes played in the match } ```Output:- A float representing the average number of goals scored per match, considering only the matches where the player played at least 45 minutes. If no such matches exist, return 0.0.Example:```pythonmatches = [ {'goals_scored': 2, 'minutes_played': 90}, {'goals_scored': 1, 'minutes_played': 45}, {'goals_scored': 0, 'minutes_played': 44}, # This match should not be considered {'goals_scored': 3, 'minutes_played': 60}]average_goals = calculate_average_goals(matches)print(average_goals) # Output should be 2.0```
answer:def calculate_average_goals(matches): total_goals = 0 valid_matches = 0 for match in matches: if match['minutes_played'] >= 45: total_goals += match['goals_scored'] valid_matches += 1 if valid_matches == 0: return 0.0 else: return total_goals / valid_matches
question:Write a python function to calculate the total distance a young runner covers in multiple charity runs, given a list of distances they ran in each event. The function should take a list of integers as input, where each integer represents the distance (in kilometers) of a single run. The function should return the total distance covered across all runs.Input: A list of non-negative integers, where each integer represents the distance of a charity run.Output: An integer representing the total distance covered in all the runs.Example:```pythondistances = [5, 10, 3, 8] # The runner participated in four charity runs covering these distances.result = total_distance(distances)print(result) # Output should be 26, as 5 + 10 + 3 + 8 = 26.```
answer:def total_distance(distances): total = 0 for distance in distances: total += distance return total
