The keys must be strings, the values must be appropriate for %()s string interpolation. Note that `__name__‘ is always an intrinsic default; its value is the section‘s name. sections() #取所有的section名字 return all the configuration section names, sans DEFAULT has_section(section) return whether the given section exists has_option(section, option) return whether the given option exists in the given section options(section) #获取所有的配置表名字key return list of configuration options for the named section read(filenames) read and parse the list of named configuration files, given by name. A single filename is also allowed. Non-existing files are ignored. Return list of successfully read files. readfp(fp, filename=None) read and parse one configuration file, given as a file object. The filename defaults to fp.name; it is only used in error messages (if fp has no `name‘ attribute, the string `<???>‘ is used). get(section, option, raw=False, vars=None) return a string value for the named option. All % interpolations are expanded in the return values, based on the defaults passed into the constructor and the DEFAULT section. Additional substitutions may be provided using the `vars‘ argument, which must be a dictionary whose contents override any pre-existing defaults. getint(section, options) like get(), but convert value to an integer getfloat(section, options) like get(), but convert value to a float getboolean(section, options) like get(), but convert value to a boolean (currently case insensitively defined as 0, false, no, off for False, and 1, true, yes, on for True). Returns False or True. items(section, raw=False, vars=None) return a list of tuples with (name, value) for each option in the section. remove_section(section) remove the given file section and all its options remove_option(section, option) remove the given option from the given section set(section, option, value) set the given option write(fp) write the configuration state in .ini format add_section(self, section) method of ConfigParser.ConfigParser instance Create a new section in the configuration. ‘‘‘
