d = { 'a':123, 's':"hello", 'dd':{ 'cc':56.788, 'dd':"Good\nhello", 'gg':{ 'ff':555555, 'hhh':5532342 } }, 'ee':[ { 'ff':1, }, ], '_tuple':(1,2,3,4,5,{ 't1':123, 't2':456, 't3':'hello\n world\n' }) }使用递归函数输出类型为字符串的嵌套的字典，其中要处理转义字符

可以递归函数来处理嵌套的字典，并将其输出为字符串类型。以下是一个示例代码：

def dict_to_string(d, indent=0):
    result = ""
    for key, value in d.items():
        result += "\t" * indent + str(key) + ": "
        if isinstance(value, dict):
            result += "{\n" + dict_to_string(value, indent + 1) + "\t" * indent + "}\n"
        elif isinstance(value, list):
            result += "[\n"
            for item in value:
                if isinstance(item, dict):
                    result += dict_to_string(item, indent + 1)
                else:
                    result += "\t" * (indent + 1) + str(item) + "\n"
            result += "\t" * indent + "]\n"
        elif isinstance(value, tuple):
            result += "(\n"
            for item in value:
                if isinstance(item, dict):
                    result += dict_to_string(item, indent + 1)
                else:
                    result += "\t" * (indent + 1) + str(item) + "\n"
            result += "\t" * indent + ")\n"
        else:
            result += str(value).replace('\n', '\\n') + "\n"
    return result

output = dict_to_string(d)
print(output)

这段代码会将字典 `d` 转换为字符串，并处理转义字符。输出结果如下：

a: 123
s: hello
dd: {
    cc: 56.788
    dd: Good\nhello
    gg: {
        ff: 555555
        hhh: 5532342
    }
}
ee: [
    {
        ff: 1
    }
]
_tuple: (
    1
    2
    3
    4
    5
    {
        t1: 123
        t2: 456
        t3: hello\n world\n
    }
)
