question:I am trying to build a simple chatbot using Python. I want to make it respond to specific keywords. Can you provide me with a basic example of how to do this?
answer:def chatbot_response(user_input): Basic chatbot that responds to specific keywords. Args: user_input (str): The user's input string. Returns: str: The chatbot's response. user_input = user_input.lower() if "hello" in user_input: return "Hi there! How can I help you today?" elif "bye" in user_input: return "Goodbye! Have a great day!" elif "help" in user_input: return "Sure, I'm here to assist you. What do you need help with?" else: return "I'm sorry, I don't understand that. Can you please rephrase?" # Example usage # print(chatbot_response("hello"))
question:The goal is to write a Python script that: 1. **Reads a text file containing a list of words, one per line.** 2. **Calculates the frequency of each word in the file.** 3. **Prints the frequency of each word in descending order of frequency.** Here's the Python code: ```python def word_frequency(filename): Calculates the frequency of each word in a text file. Args: filename: The name of the text file. Returns: A dictionary where keys are words and values are their frequencies. word_counts = {} with open(filename, 'r') as file: for line in file: words = line.lower().split() for word in words: if word in word_counts: word_counts[word] += 1 else: word_counts[word] = 1 return word_counts
answer:def word_frequency(filename): Calculates the frequency of each word in a text file. Args: filename: The name of the text file. Returns: A dictionary where keys are words and values are their frequencies in descending order. from collections import Counter with open(filename, 'r') as file: words = file.read().lower().split() word_counts = Counter(words) sorted_word_counts = dict(sorted(word_counts.items(), key=lambda item: item[1], reverse=True)) return sorted_word_counts
question:This code snippet is written in Python. It defines a function named `count_vowels` that takes a string as input and returns the number of vowels present in the string.
answer:def count_vowels(s): Returns the number of vowels present in the string s. vowels = 'aeiouAEIOU' count = 0 for char in s: if char in vowels: count += 1 return count
question:This is a sample text: **Sample Text:** "The quick brown fox jumps over the lazy dog." **Instructions:** * Create a Python function that takes a string as input and returns a dictionary containing the frequency of each character in the string. ```python def char_frequency(text): This function takes a string as input and returns a dictionary containing the frequency of each character in the string. Args: text: The input string. Returns: A dictionary where the keys are the unique characters in the string and the values are their corresponding frequencies.
answer:def char_frequency(text): This function takes a string as input and returns a dictionary containing the frequency of each character in the string. Args: text: The input string. Returns: A dictionary where the keys are the unique characters in the string and the values are their corresponding frequencies. frequency = {} for char in text: if char in frequency: frequency[char] += 1 else: frequency[char] = 1 return frequency
