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

Sure, 我可以用Python来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。以下是Python代码示例：

import random

# Generate a random number with a random length and random decimal places
def generate_num():
    length = random.randint(1,4)
    decimal = random.randint(0,2)
    num = round(random.uniform(0,10**length), decimal)
    return num

# Generate a random operator
def generate_operator():
    operators = ['+', '-', '*', '/']
    return random.choice(operators)

# Generate a random expression with a random length and random structure
def generate_expression(length):
    if length == 1:
        return str(generate_num())
    else:
        num = generate_num()
        operator = generate_operator()
        if operator in ['+', '-']:
            return f'{num} {operator} {generate_expression(length - 1)}'
        else:
            return f'({num} {operator} {generate_expression(length - 1)})'

# Generate a random expression with a random length between 1 and 10
expression_length = random.randint(1,10)
expression = generate_expression(expression_length)
print(expression)

希望这个程序可以帮到你。如果你还有其他问题，欢迎继续问我。
