python配置文件有.conf，.ini，.txt等多种
python集成的 标准库的 ConfigParser 模块提供一套 API 来读取和操作配置文件
我的配置文件如下
1 [MOTOR] 2 comnum = 3 3 baud = 19200 4 m1slowstep = 10 5 m1faststep = 100 6 m1origin = 5 7 m2slowstep = 10 8 m2faststep = 50 9 m2origin = 5 10 11 [CoarseAdjust] 12 standardx = 0.000000 13 standardy = 0.000000 14 xperangle = 500 15 yperangle = 160 16 xmotor = 1 17 xmotororien = -1 18 ymotor = 2 19 ymotororien = 1 20 triggermode = 1 21 triggertimeout = 1 22 autoadjust = 1 23 24 [FineAdjust] 25 countdown = 10 26 datfilepath = E:\Mcs05\DatTemp27 xfinestep = 10 28 yfinestep = 10 29 mcsfilepath = E:\Mcs05\WHTest30 filetype = Mcs 31 nastartaltitude = 80 32 naendaltitude = 111 33 rayleighstartaltitude = 20 34 rayleighendaltitude = 60 35 fineadjustfilepath = E:\Mcs0536 methodselect = 01 37 38 [EASYMCS] 39 chname = WHTest 40 prefixion = R 41 mcstheshold = 1.4 42 numofbins = 2048 43 binwidth = 640 44 numofpluse = 30 45 mcs32path = D:\software\MCS3246 mcs32filepath = E:\Mcs0547 48 [GYRO] 49 comno = 15 50 baud = 9600
当我进行读写操作时，发现
1 # 读取配置文件 2 import ConfigParser 3 config = ConfigParser.ConfigParser() 4 config.readfp(open(‘GloVar.ini‘)) 5 a = config.get("CoarseAdjust","MD5") 6 print a 7 8 # 写入配置文件 9 import ConfigParser 10 config = ConfigParser.ConfigParser() 11 # set a number of parameters 12 config.add_section("CoarseAdjust") 13 config.set("CoarseAdjust", "xperangle", "1000") 14 config.set("CoarseAdjust", "yperangle", "500")
发现配置文件中的内容并没有发生改变，为什么？
上面的这种修改方式只是修改了python中内存的值，并没有对配置文件的内容进行修改，并真实地写入
真正地修改方式应该是
1 """修改并保存在配置文件中""" 2 # coding:utf-8 3 import configparser 4 5 # 创建管理对象 6 conf = configparser.ConfigParser() 7 conf.read(‘GloVar.ini‘, encoding=‘utf-8‘) 8 print(conf.sections()) 9 10 # 往section添加key和value 11 conf.set("CoarseAdjust", "xPerAngle", "{}".format(500)) 12 conf.set("CoarseAdjust", "yPerAngle", "160") 13 items = conf.items(‘CoarseAdjust‘) 14 print(items) # list里面对象是元祖 15 16 conf.write(open(‘GloVar.ini‘, "r+", encoding="utf-8")) # r+模式
ConfigParser 模块需要注意的是
