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...
The main goal in this tutorial will be to read and understand the file with Python and then fix the problems. First, you need to read the file with ElementTree. tree = ET.parse('movies.xml') root = tree.getroot() Run code Powered By Now that you have initialized the tree, you ...

This will show you how we can encapsulate some not-quite-functional features of Python to create an iterable sequence of values. We'll make use of the xml.etree module. After parsing, the resulting ElementTree object has a findall() method that will iterate through the available values. We...
4.1 Python内置的标准模块模块是开发者开发程序的利器。正是因为有了标准模块,使得开发者宛如站在巨人的肩膀上。那么,Python到底有哪些内置的标准模块可供直接使用,又如何去获知这些模块的信息?通过以下两种方法可以查看Python内置的标准模块及其说明。4.1.1 通过help()命令查看内置模块通过“cmd”命令进入命令行方式,...
