生成50道100以內加减去算式的混合习题,题中不能有相同的算式。 2、同时将加法算式与减法算式的产生模块进行分离。 3、设计好基本的测试数据集,进行测试

我可以帮你生成一组满足条件的混合算术习题。首先,我们将创建两个独立的模块,一个用于生成100以内不重复的加法算式,另一个用于生成减法算式。然后,我们会随机组合这些算式以形成混合题。
**生成加法算式模块**:
```python
import random
def generate_addition(num_questions):
addition_pairs = set()
while len(addition_pairs) < num_questions:
a, b = random.randint(1, 100), random.randint(1, 100)
if (a, b) not in addition_pairs and (b, a) not in addition_pairs:
addition_pairs.add((a, b))
return [(f"{a} + {b}", a + b) for a, b in addition_pairs]
```
**生成减法算式模块**:
```python
def generate_subtraction(num_questions):
subtraction_pairs = set()
while len(subtraction_pairs) < num_questions:
a, b = random.randint(1, 100), random.randint(a+1, 100) # 防止除数为零
if (a, b) not in subtraction_pairs and (b, a) not in subtraction_pairs:
subtraction_pairs.add((a, b))
return [(f"{a} - {b}", a - b) for a, b in subtraction_pairs]
```
**组合并测试**:
```python
num混合题 = 50
addition_problems = generate_addition(num混合题 // 2)
subtraction_problems = generate_subtraction(num混合题 // 2)
# 检查是否有足够的减法题目
if num混合题 % 2 == 1:
subtraction_problems.append(random.choice(subtraction_problems)) # 添加一个剩余的减法题
mixed_problems = addition_problems + subtraction_problems[:]
# 测试数据集
test_data = [(question, answer) for question, answer in mixed_problems]
print("混合算术习题:")
for i, (q, a) in enumerate(test_data):
print(f"第{i + 1}: {q}, 答案: {a}")
