使用python解析文件的最佳方法

# 读取文本文件
with open('example.txt', 'r') as file:
    content = file.read()
    print(content)

# 写入文本文件
with open('output.txt', 'w') as file:
    file.write('Hello, World!')

import csv

# 读取CSV文件
with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    for row in reader:
        print(row)

# 写入CSV文件
with open('output.csv', 'w', newline='') as file:
    writer = csv.writer(file)
    writer.writerow(['Name', 'Age'])
    writer.writerow(['Alice', 30])

import json

# 读取JSON文件
with open('data.json', 'r') as file:
    data = json.load(file)
    print(data)

# 写入JSON文件
with open('output.json', 'w') as file:
    json.dump({'name': 'Alice', 'age': 30}, file, indent=4)

import xml.etree.ElementTree as ET

# 解析XML文件
tree = ET.parse('data.xml')
root = tree.getroot()

for child in root:
    print(child.tag, child.attrib)

# 创建XML文件
root = ET.Element("root")
doc = ET.SubElement(root, "doc")

field1 = ET.SubElement(doc, "field1")
field1.set("name", "firstname")
field1.text = "Alex"

tree = ET.ElementTree(root)
tree.write("output.xml")

# 读取二进制文件
with open('image.jpg', 'rb') as file:
    data = file.read()
    print(data[:10])  # 打印前10个字节

# 写入二进制文件
with open('output.bin', 'wb') as file:
    file.write(b'\x00\x01\x02\x03\x04\x05\x06\x07\x08\x09')

with open('example.txt', 'r', encoding='utf-8') as file:
    content = file.read()

import os
if os.path.exists('example.txt'):
    with open('example.txt', 'r') as file:
        content = file.read()

import os
if os.access('example.txt', os.R_OK):
    with open('example.txt', 'r') as file:
        content = file.read()
