Python编写的小学加减乘除算术练习题源码
以下是一个简单的Python源码，用于生成小学加减乘除算术练习题： ```python import random def generate_question(): num1 = random.randint(1, 10) num2 = random.randint(1, 10) operator = random.choice(["+", "-", "*", "/"]) if operator == "+": question = f"{num1} + {num2}" answer = num1 + num2 elif operator == "-": question = f"{num1} - {num2}" answer = num1 - num2 elif operator == "*": question = f"{num1} * {num2}" answer = num1 * num2 else: if num2 != 0: question = f"{num1
马上放暑假了，用python开发了一个，小学加减乘除算术练习题自动出题工具，可以自动出题，自动判断对错。
