基于Python设计额一个随机生成四则运算题目的小程序源码.zip

import random # 生成随机整数 def generate_random_number(): return random.randint(1, 100) # 生成随机运算符 def generate_random_operator(): operators = ['+', '-', '*', '/'] return random.choice(operators) # 生成随机四则运算题目 def generate_math_question(): num1 = generate_random_number() num2 = generate_random_number() operator = generate_random_operator() if operator == '/': # 除法运算，确保结果是整数 num1 = num1 * num2 elif operator == '-': # 减法运算，确保结果不为负数 num1, num2 = max(num1, num2), min(num1, num2) question = f"{num1} {operator} {num2}" answer = eval(question) return question, answer # 生成指定数量的四则运算题目 def generate_math_questions(num_questions): questions = [] for _ in range(num_questions): question, answer = generate_math_question() questions.append((question, answer)) return questions # 示例用法 num_questions = 5 # 题目数量 questions = generate_math_questions(num_questions) for i, (question, answer) in enumerate(questions, start=1): print(f"题目 {i}: {question} = ?") user_answer = int(input("你的答案: ")) if user_answer == answer: print("回答正确!") else: print(f"错误，正确答案是： {answer}.")
