Complete the code to define the main component responsible for handling search queries.
class [1]Handler: def __init__(self, data_source): self.data_source = data_source def search(self, query): # Implementation to search data_source pass
The main class handling search queries should be named SearchHandler to clearly represent its responsibility.
Complete the code to add a filter method that narrows down results based on a condition.
class FilterHandler: def __init__(self, items): self.items = items def filter(self, condition): return [item for item in self.items if item.[1](condition)]
The method contains is commonly used to check if an item includes a condition, suitable for filtering.
Fix the error in the code to correctly combine search and filter results.
def search_and_filter(data, query, filter_condition): search_results = [item for item in data if query in item] filtered_results = [item for item in search_results if item.[1](filter_condition)] return filtered_results
The contains method is appropriate to check if the item includes the filter condition.
Fill both blanks to create a dictionary comprehension that maps items to their lengths only if length is greater than 3.
length_map = {item: len(item) for item in items if len(item) [1] 3 and 'a' [2] item}The condition checks if length is greater than 3 and if 'a' is in the item.
Fill all three blanks to create a filtered dictionary with uppercase keys and values greater than 10.
filtered_dict = {item[1]: value for item, value in data.items() if value [2] 10 and item[3]('x')}The keys are converted to uppercase, values filtered greater than 10, and keys starting with 'x'.
