用Python写一个随机生成任意长度带括号带小数带分数的算式的程序

好的，我可以回答这个问题。以下是Python的代码示例：

import random

def generate_expression():
    # 生成随机长度并在括号内添加随机数字
    expression = ""
    for i in range(random.randint(1, 5)):
        rand_num = round(random.uniform(0, 10), 2)
        if rand_num.is_integer():
            expression += f"{int(rand_num)} "
        else:
            expression += f"{rand_num} "
            
        if random.choice([True, False]):
            expression = f"({expression}) "
            
    # 添加运算符和随机数字
    operators = ["+", "-", "*", "/"]
    for i in range(random.randint(1, 5)):
        expression += random.choice(operators) + " "
        rand_num = round(random.uniform(0, 10), 2)
        if rand_num.is_integer():
            expression += f"{int(rand_num)} "
        else:
            expression += f"{rand_num} "
            
    # 生成不带括号的随机数字
    rand_num = round(random.uniform(0, 10), 2)
    if rand_num.is_integer():
        expression += f"{int(rand_num)} "
    else:
        expression += f"{rand_num} "
        
    return expression

print(generate_expression())

这个程序可以生成带有随机长度、随机数字、随机运算符和括号的算式。你可以随时运行程序来生成不同的算式。
