如何从内部有列表的字典中打印句子提取信息

从内部有列表的字典中打印句子提取信息的方法如下:

  1. 首先,我们需要定义一个包含字典和列表的数据结构。例如:
代码语言:txt
复制
data = {
    "name": "John",
    "age": 25,
    "hobbies": ["reading", "swimming", "coding"]
}
  1. 接下来,我们可以使用字符串格式化的方式将列表中的元素提取出来并打印出来。例如:
代码语言:txt
复制
sentence = "My name is {name}. I am {age} years old. My hobbies are {hobbies}."

hobbies_str = ", ".join(data["hobbies"])  # 将列表转换为字符串

print(sentence.format(name=data["name"], age=data["age"], hobbies=hobbies_str))

输出结果为:

代码语言:txt
复制
My name is John. I am 25 years old. My hobbies are reading, swimming, coding.
  1. 如果字典中的某个键对应的值是一个嵌套的字典或列表,我们可以使用递归的方式进行提取。例如:
代码语言:txt
复制
data = {
    "name": "John",
    "age": 25,
    "hobbies": ["reading", "swimming", "coding"],
    "address": {
        "city": "New York",
        "country": "USA"
    }
}

sentence = "My name is {name}. I am {age} years old. My hobbies are {hobbies}. I live in {city}, {country}."

hobbies_str = ", ".join(data["hobbies"])  # 将列表转换为字符串

print(sentence.format(name=data["name"], age=data["age"], hobbies=hobbies_str, city=data["address"]["city"], country=data["address"]["country"]))

输出结果为:

代码语言:txt
复制
My name is John. I am 25 years old. My hobbies are reading, swimming, coding. I live in New York, USA.

这样,我们就可以从内部有列表的字典中打印句子并提取信息了。
