configparser:都会按照字符串进行处理
import configparser
config = configparser.ConfigParser()
config.read(‘xxxooo‘, encoding=‘utf-8‘)
练习：
import configparser
config = configparser.ConfigParser()
config.read(‘f1‘,encoding=‘utf-8‘)
ret = config.sections()
print(ret)
ret = config.items("section2")
print(ret)
ret = config.options(‘section2‘)
print(ret)
v = config.get(‘section1‘, ‘k1‘)
print(v)
has_sec = config.has_section(‘section1‘)
print(has_sec)
# config.add_section("section3")
# config.write(open(‘xxxooo‘, ‘w‘))
#
# config.remove_section("section3")
# config.write(open(‘xxxooo‘, ‘w‘))
has_opt = config.has_option(‘section1‘, ‘k1‘)
print(has_opt)
config.remove_option(‘section1‘, ‘k1‘)
config.write(open(‘xxxooo‘, ‘w‘))
config.set(‘section1‘, ‘k10‘, "123")
config.write(open(‘xxxooo‘, ‘w‘))
XML：
浏览器返回的字符串
1,html
2,json
3,xml
页面上做展示（字符串类型的一个XML格式数据）
配置文件（文件，内部数据XML格式）
每一个节点都是 element的对象
练习1：
from xml.etree import ElementTree as ET
tree = ET.parse(‘xo.xml‘)
root = tree.getroot()
for child in root:
print(child.tag,child.attrib)
for grandchild in child:
print(grandchild.tag,grandchild.attrib)
str_xml = open(‘xo.xml‘, ‘r‘).read()
root = ET.XML(str_xml)
for node in root.iter(‘year‘):
new_year = int(node.text) + 1
node.text = str(new_year)
# 设置属性
node.set(‘name‘, ‘alex‘)
node.set(‘age‘, ‘18‘)
# 删除属性
del node.attrib[‘name‘]
tree = ET.ElementTree(root)
tree.write(‘new.xml‘,encoding=‘utf-8‘)
tree = ET.parse(‘xo.xml‘)
root = tree .getroot()
for node in root.iter(‘year‘):
new_year = int(node.text) + 1
node.text = str(new_year)
node.set(‘age‘,‘18‘)
node.set(‘name‘,‘sxl‘)
del node.attrib[‘name‘]
tree.write(‘new2.xml‘,encoding=‘utf-8‘)
练习2：
from xml.etree import ElementTree as ET
from xml.dom import minidom
def prettify(elem):
"""将节点转换成字符串，并添加缩进。
"""
rough_string = ET.tostring(elem, ‘utf-8‘)
reparsed = minidom.parseString(rough_string)
return reparsed.toprettyxml(indent="\t")
root = ET.Element(‘famliy‘)
son1 = ET.Element(‘son1‘,{‘name‘:‘大儿子‘})
son2 = ET.Element(‘son2‘,{‘name‘:‘小儿子‘})
grandson1 = ET.Element(‘grandson‘, {‘name‘: ‘儿11‘})
grandson2 = ET.Element(‘grandson‘, {‘name‘: ‘儿22‘})
son1.append(grandson1)
son2.append(grandson2)
root.append(son1)
root.append(son2)
raw_str = prettify(root)
tree = ET.ElementTree(root)
tree.write(‘oooo.xml‘,encoding=‘utf-8‘, short_empty_elements=False)
f = open("xxxoo.xml",‘w‘,encoding=‘utf-8‘)
f.write(raw_str)
f.close()
