一、subprocess模式
# import os
# while True:
# cmd=input('>>').strip()
# if not cmd:continue
# if cmd=='q':break
# os.system(cmd) import subprocess
obj=subprocess.Popen('dir',
shell=True,
stdout=subprocess.PIPE,
stderr=subprocess.PIPE
)
res1=obj.stdout.read()
res3=obj.stdout.read()
res2=obj.stderr.read()
print('right:',res1.decode('gbk'))
print('error:',res2.decode('gbk')) print('res3:',res3.decode('gbk'))
二、configparser模块
import configparser config=configparser.ConfigParser()
config.read('a.cfg',encoding='utf-8') #删除整个标题section2
config.remove_section('section2') #删除标题section1下的某个k1和k2
config.remove_option('section1','k1')
config.remove_option('section1','k2') #判断是否存在某个标题
print(config.has_section('section1')) #判断标题section1下是否有user
print(config.has_option('section1','')) #添加一个标题
config.add_section('egon') #在标题egon下添加name=egon,age=18的配置
config.set('egon','name','egon')
config.set('egon','age',18) #报错,必须是字符串 #最后将修改的内容写入文件,完成最终的修改
config.write(open('a.cfg','w'))
