可以使用Python编写一个小学四则运算题目生成器,代码如下:
```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, 100)
denominator = random.randint(numerator+1, 100)
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()
operator1 = generate_operator()
operator2 = generate_operator()
if operator1 in ["*", "/"] and operator2 in ["+", "-"]:
question = "({} {} {}) {} {}".format(num1, operator1, num2, operator2, generate_number())
else:
question = "{} {} {} {} {}".format(num1, operator1, num2, operator2, generate_number())
return question
# 生成指定数量的题目
def generate_questions(num):
questions = []
for i in range(num):
question = generate_question()
questions.append(question)
return questions
# 测试
questions = generate_questions(10)
for question in questions:
print(question)
```
这个程序可以生成指定数量的小学四则运算题目,包括整数和真分数的加减乘除运算。如果需要支持更多的运算符或者调整数字的范围,可以在代码中进行修改。
