Python基础-configparser和hashlib模块

configparser模块

import configparser

config = configparser.ConfigParser()

#将配置写入到文件

config['DEFAULT'] = {'ServerAliveInterval': '',

                     'Compression': 'yes',

                     'CompressionLevel': ''}

config['bitbucket.org'] = {'User': 'fansik'}

config['www.fansik.com'] = {'Host Port': '',

                            'ForwardX11': 'no'}

config['DEFAULT']['ForwardX11'] = 'yes'

with open('example.ini', 'w') as configfile:

    config.write(configfile)

# 读取配置

config.read('example.ini', encoding='utf8')

print(config.sections())

print(config.defaults())

for key in config['bitbucket.org']: # 这个key包含DEFAULT中的内容

    print(key)

# 修改配置

config.remove_section('bitbucket.org')

config.has_section('bitbucket.org') # 判断是否删除成功

config.write(open('example.ini', 'w'))

# 修改单个的配置

config.set('www.fansik.com', 'forwardx11', 'yes')

# 删除单个配置

config.remove_option('www.fansik.com', 'forwardx11')

hashlib加密模块

import hashlib

password = hashlib.md5()

password.update('fanjinbao'.encode('utf8'))

print(password)

print(password.hexdigest())

password.update('fansik'.encode('utf8'))

print(password.hexdigest())

password2 = hashlib.sha256()

password2.update('fanjinbao'.encode('utf8'))

print(password2.hexdigest())

password3 = hashlib.sha256()

password3.update('fanjinbao'.encode('utf8'))

print(password2.hexdigest())
