如何将Python的dump输出转换为其他格式

要将Python的pickle.dump()输出转换为其他格式，您需要首先使用pickle.load()加载数据，然后将其写入所需的格式

1. JSON:

import pickle
import json

# 假设你已经有一个名为data.pkl的pickle文件
with open('data.pkl', 'rb') as f:
    data = https://www.yisu.com/ask/pickle.load(f)'data.json', 'w', encoding='utf-8') as f:
    json.dump(data, f, ensure_ascii=False, indent=4)

2. CSV:

import pickle
import csv

# 假设你已经有一个名为data.pkl的pickle文件
with open('data.pkl', 'rb') as f:
    data = https://www.yisu.com/ask/pickle.load(f)'data.csv', 'w', newline='', encoding='utf-8') as f:
    writer = csv.writer(f)
    for row in data:
        writer.writerow(row)

3. XML:

import pickle
from xml.etree.ElementTree import Element, SubElement, tostring
from xml.dom.minidom import parseString

# 假设你已经有一个名为data.pkl的pickle文件
with open('data.pkl', 'rb') as f:
    data = https://www.yisu.com/ask/pickle.load(f)'root')
for item in data:
    elem = SubElement(root, 'item')
    elem.text = str(item)

xml_str = parseString(tostring(root)).toprettyxml(indent="   ")

# 保存到文件中
with open('data.xml', 'w', encoding='utf-8') as f:
    f.write(xml_str)

请注意，这些示例仅适用于简单的数据结构。对于更复杂的数据类型，您可能需要编写自定义的序列化和反序列化函数。在处理不同格式时，请确保安装了必要的库。
