好的,这个问题可以回答。以下是一个简单的 Python 代码示例,可以生成小学四则运算题目,包括整数和真分数:
```python
import random
# 生成随机的整数或真分数
def generate_number():
if random.random() < 0.5:
return random.randint(1, 100)
else:
numerator = random.randint(1, 10)
denominator = random.randint(numerator + 1, 20)
return "{}/{}".format(numerator, denominator)
# 生成随机的运算符
def generate_operator():
operators = ["+", "-", "*", "/"]
return random.choice(operators)
# 生成四则运算题目
def generate_question():
num1 = generate_number()
num2 = generate_number()
operator = generate_operator()
if operator == "+":
answer = num1 + num2
elif operator == "-":
answer = num1 - num2
elif operator == "*":
answer = num1 * num2
else:
answer = num1 / num2
return "{} {} {} =".format(num1, operator, num2), answer
# 生成指定数量的题目
def generate_questions(num):
questions = []
answers = []
for i in range(num):
question, answer = generate_question()
questions.append(question)
answers.append(answer)
return questions, answers
# 测试代码,生成10道题目
questions, answers = generate_questions(10)
for i in range(10):
print("{} {}".format(questions[i], answers[i]))
```
这个代码可以生成指定数量的小学四则运算题目,包括整数和真分数,每个题目都有一个正确答案。
