如何在python中读取具有特定数据类型的文件内容，而不是作为字符串？

import csv

with open('data.csv', 'r') as file:
    reader = csv.reader(file)
    for row in reader:
        # 处理每一行数据
        print(row)

import json

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

import pandas as pd

data = pd.read_excel('data.xlsx')
# 处理Excel数据
print(data)

import xlrd

workbook = xlrd.open_workbook('data.xlsx')
worksheet = workbook.sheet_by_index(0)

for row in range(worksheet.nrows):
    for col in range(worksheet.ncols):
        # 处理每个单元格数据
        cell_value = worksheet.cell_value(row, col)
        print(cell_value)

import xml.etree.ElementTree as ET

tree = ET.parse('data.xml')
root = tree.getroot()

# 处理XML数据
for child in root:
    print(child.tag, child.attrib)
