configparser模块使用

# import configparser
#
# config = configparser.ConfigParser()
# config["DEFAULT"] = {'ServerAliveInterval': '45',
#                      'Compression': 'yes',
#                      'CompressionLevel': '9'}
#
# config['bitbucket.org'] = {}
# config['bitbucket.org']['User'] = 'hg'
# config['topsecret.server.com'] = {}
# topsecret = config['topsecret.server.com']
# topsecret['Host Port'] = '50022'  # mutates the parser
# topsecret['ForwardX11'] = 'no'  # same here
# config['DEFAULT']['ForwardX11'] = 'yes'
# with open('example.ini', 'w') as configfile:
#     config.write(configfile)

import configparser

config = configparser.ConfigParser()

#---------------------------------------------查
print(config.sections())   #[]

config.read('example.ini')

print(config.sections())   #['bitbucket.org', 'topsecret.server.com']

print('bytebong.com' in config)# False

print(config['bitbucket.org']['User']) # hg

print(config['DEFAULT']['Compression']) #yes

print(config['topsecret.server.com']['ForwardX11'])  #no


for key in config['bitbucket.org']:
    print(key)

#默认的会被打印
# user
# serveraliveinterval
# compression
# compressionlevel
# forwardx11


print(config.options('bitbucket.org'))#['user', 'serveraliveinterval', 'compression', 'compressionlevel', 'forwardx11']
print(config.items('bitbucket.org'))  #[('serveraliveinterval', '45'), ('compression', 'yes'), ('compressionlevel', '9'), ('forwardx11', 'yes'), ('user', 'hg')]
#
print(config.get('bitbucket.org','compressionlevel'))#9
#
#
#---------------------------------------------删,改,增(config.write(open('i.cfg', "w")))
#
#
config.add_section('yuan')
#
config.remove_section('topsecret.server.com')
config.remove_option('bitbucket.org','user')
#
config.set('bitbucket.org','k1','6666')

config.set('yuan','fengfeng123456','123456')
#
config.write(open('i.cfg', "w"))

导入模块需要注意

#import zyf #绝对路径，此时是找不到的，所以会报错
#永远相对于执行的路径
#F:\pythonProject\first\venv\Scripts\python.exe F:/pythonProject/first/demo2/zyf.py

from test1 import zyf  #test1\zyf.py #此时可以找到
#调用方法
print(zyf.cal.add(2,3))
