.ini 文件是Initialization File的缩写，即初始化文件，是windows的系统
配置文件所采用的存储格式，统管windows的各项配置，一般用户就用windows提供的各项图形化管理界面就可实现相同的配置了。但在某些情况，还是要直接编辑ini才方便，一般只有很熟悉windows才能去直接编辑。
开始时用于WIN3X下面，WIN95用
注册表代替，以及后面的内容表示一个节，相当于注册表中的键。
示例ini配置文件（setting.ini）：
1 [txtA] 2 name = comma,end,full,run 3 comma = 1000 4 end = 3 5 full = 2 6 run = 1 7 default_comma = 3 8 default_end = 3 9 default_full = 2 10 default_run = 1 11 12 [txtB] 13 name = comma,end,full,run 14 comma = 1000 15 end = 3 16 full = 2 17 run = 1 18 default_comma = 3 19 default_end = 3 20 default_full = 2 21 default_run = 1 22 23 [chinese] 24 name = volume,tones,speed,spokesman 25 volume = 5 26 tones = 5 27 speed = 5 28 spokesman = 1 29 default_volume = 5 30 default_tones = 5 31 default_speed = 5 32 default_spokesman = 1 33 34 [english] 35 name = volume,tones,speed,spokesman 36 volume = 5 37 tones = 5 38 speed = 5 39 spokesman = 1 40 default_volume = 5 41 default_tones = 5 42 default_speed = 5 43 default_spokesman = 1 44 45 [help] 46 47 [about]
示例ini配置文件操作程序：
1 import configparser 2 import os 3 4 5 # *** 初始化配置文件路径 *** # 6 curpath = os.path.dirname(os.path.realpath(__file__)) # 当前文件路径 7 inipath = os.path.join(curpath, "setting.ini") # 配置文件路径（组合、相对路径） 8 9 # *** 数据读取 *** # 10 conf = configparser.ConfigParser() 11 conf.read(inipath, encoding="utf-8") 12 # sections = conf.sections() # 获取所有的sections名称 13 # options = conf.options(sections[0]) # 获取section[0]中所有options的名称 14 # items = conf.items(sections[0]) # 获取section[0]中所有的键值对 15 # value = conf.get(sections[-1],'txt2') # 获取section[-1]中option的值，返回为string类型 16 # value1 = conf.getint(sections[0],'comma') # 返回int类型 17 # value2 = conf.getfloat(sections[0],'end') # 返回float类型 18 # value3 = conf.getboolean(sections[0],'run') # 返回boolen类型 19 20 # *** 删除内容 *** # 21 # conf.remove_option(sections[0], "comma") 22 # conf.remove_section(sections[1]) 23 24 # *** 修改内容 *** # 25 conf.set('txtB', "comma", "1000") 26 conf.write(open(inipath, "r+", encoding="utf-8")) # r+模式 27 28 29 # print(conf.items(sections[0]) )
