一、shelve模块
1 import shelve 2 3 # 基于pickle模块, 4 5 d = shelve.open(‘shelve_test‘) 6 7 8 class Test(object): 9 def __init__(self, n): 10 self.n = n 11 12 t1 = Test(123) 13 t2 = Test(456) 14 name = [‘alex‘, ‘rain‘, ‘test‘] 15 d[‘test‘] = name 16 d[‘t1‘] = t1 17 d[‘t2‘] = t2 18 19 d.close()
二、XML模块
1.增、删、改、查
import xml.etree.ElementTree as ET tree = ET.parse("list.xml") root = tree.getroot() print(root.tag) # 查询 # # 遍历xml文档 # for child in root: # print(child.tag, child.attrib) # for i in child: # print(i.tag, i.text) # 只遍历year 节点 # for node in root.iter(‘year‘): # print(node.tag, node.text) # 修改 # for node in root.iter(‘year‘): # new_year = int(node.text) + 1 # node.text = str(new_year) # node.set("updated", "yes") # # tree.write("xmltest.xml") # 删除node # for country in root.findall(‘country‘): # rank = int(country.find(‘rank‘).text) # if rank > 50: # root.remove(country) # # tree.write(‘output.xml‘)
2.创建
1 import xml.etree.ElementTree as ET 2 3 # root 4 new_xml = ET.Element("namelist") 5 6 7 name = ET.SubElement(new_xml, "name", attrib={"enrolled": "yes"}) 8 age = ET.SubElement(name, "age", attrib={"checked": "no"}) 9 sex = ET.SubElement(name, "sex") 10 sex.text = ‘33‘ 11 name2 = ET.SubElement(new_xml, "name", attrib={"enrolled": "no"}) 12 age = ET.SubElement(name2, "age") 13 age.text = ‘19‘ 14 15 # 生成文档对象 16 et = ET.ElementTree(new_xml) 17 et.write("test.xml", encoding="utf-8", xml_declaration=True)
三、shutil模块
1 import shutil 2 # http://www.cnblogs.com/wupeiqi/articles/4963027.html 3 4 # copy fileobj 5 # f1 = open(‘access.log‘) 6 # f2 = open("access1.log", ‘w‘) 7 # shutil.copyfileobj(f1, f2, length=1024) 8 9 # copy file 10 # shutil.copyfile(‘access.log‘, ‘access2.log‘) 11 12 # 仅拷贝权限。内容、组、用户均不变 13 # shutil.copymode() 14 15 # 拷贝状态的信息，包括：mode bits, atime, mtime, flags. 内容不变 16 # shutil.copystat() 17 18 # copy 目录
四、subprocess模块
1 import subprocess 2 3 res = subprocess.Popen("pwd", shell=True, stdout=subprocess.PIPE, stderr=subprocess.PIPE, cwd="/") 4 print(res.stdout.read()) 5 6 # res.poll() 7 # res.terminate() 8 # res.wait() 9 10 subprocess.getstatusoutput("ls")
五、RE模块
import re # 从头匹配,很少使用 re.match("\d+", "341221") # 匹配一次 re.search("\d+", "341221") # 匹配多次 re.findall("\d+", "341221") # 以逗号分割 re.split(",", "341,221") # 匹配到进行替换,默认是替代所有,count指定次数. re.sub("\d{4}", "1995", "1399,2017", count=1) # re.I (忽略大小写) # print(re.search("[a-z]", "Alex", flags=re.I)) # re.M (匹配多行) # print(re.search("^is", "my name\nis alex", flags=re.M)) # re.S (多行匹配在一起) # print(re.search(".+", "my \nname", flags=re.S))
六、configparser模块
1 mport configparser 2 3 config = configparser.ConfigParser() 4 config["DEFAULT"] = {‘ServerAliveInterval‘: ‘45‘, 5 ‘Compression‘: ‘yes‘, 6 ‘CompressionLevel‘: ‘9‘} 7 8 config[‘bitbucket.org‘] = {} 9 config[‘bitbucket.org‘][‘User‘] = ‘hg‘ 10 config[‘topsecret.server.com‘] = {} 11 topsecret = config[‘topsecret.server.com‘] 12 topsecret[‘Host Port‘] = ‘50022‘ # mutates the parser 13 topsecret[‘ForwardX11‘] = ‘no‘ # same here 14 config[‘DEFAULT‘][‘ForwardX11‘] = ‘yes‘ 15 with open(‘example.ini‘, ‘w‘) as configfile: 16 config.write(configfile)
