在这一步中,我们导入Python的内置库xml.etree.ElementTree,用于解析XML文件。 步骤2:打开XML文件 tree=ET.parse('file.xml')root=tree.getroot() 1. 2. 这里我们使用ElementTree库中的ET.parse方法来打开XML文件,并使用getroot()方法获取XML文件的根节点。 步骤3:读取XML数据 data=[]forchildinroot:data.append...

除了xml.etree.ElementTree和lxml之外,还有一个方便的库,即xmltodict,它将XML解析为Python的字典格式,使得对XML的处理更加直观。 首先,确保已安装xmltodict库: pip install xmltodict 1. 接下来,我们使用xmltodict解析XML文件: import xmltodict with open('example.xml', 'r') as file: xml_data = file.read() ...

Python File read() 方法 Python File(文件) 方法 概述 read() 方法用于从文件读取指定的字节数,如果未给定或为负则读取所有。 语法 read() 方法语法如下: fileObject.read([size]); 参数 size -- 从文件中读取的字节数,默认为 -1,表示读取整个文件。
The XML file provided describes a basic collection of movies. The only problem is that the data is a mess! There have been many different curators of this collection, and everyone has their own way of entering data into the file. The main goal in this tutorial will be to read and unders...
