CLASSES

class ConfigParser(RawConfigParser)
|  ConfigParser implementing interpolation.
|
|  add_section(self, section)
|      Create a new section in the configuration.  Extends
|      RawConfigParser.add_section by validating if the section
a9fa
name is
|      a string.
|
|  set(self, section, option, value=None)
|      Set an option.  Extends RawConfigParser.set by validating type and
|      interpolation syntax on the value.
|
|  defaults(self)
|
|  get(self, section, option, *, raw=False, vars=None, fallback=<object object at 0x0000000002F42120>)
|      Get an option value for a given section.
|
|  getboolean(self, section, option, *, raw=False, vars=None, fallback=<object object at 0x0000000002F42120>)
|
|  getfloat(self, section, option, *, raw=False, vars=None, fallback=<object object at 0x0000000002F42120>)
|
|  getint(self, section, option, *, raw=False, vars=None, fallback=<object object at 0x0000000002F42120>)
|
|  has_option(self, section, option)
|      Check for the existence of a given option in a given section.
|      If the specified `section' is None or an empty string, DEFAULT is
|      assumed. If the specified `section' does not exist, returns False.
|
|  has_section(self, section)
|      Indicate whether the named section is present in the configuration.

|  items(self, section=<object object at 0x0000000002F42120>, raw=False, vars=None)
|      Return a list of (name, value) tuples for each option in a section.
|
|  options(self, section)
|      Return a list of option names for the given section name.
|  popitem(self)
|      Remove a section from the parser and return it as
|  read(self, filenames, encoding=None)
|      Read and parse a filename or a list of filenames.
|      Return list of successfully read files.
|
|  read_dict(self, dictionary, source='<dict>')
|      Read configuration from a dictionary.
|
|  read_file(self, f, source=None)
|      Like read() but the argument must be a file-like object.
|
|  read_string(self, string, source='<string>')
|      Read configuration from a given string.
|
|  readfp(self, fp, filename=None)
|      Deprecated, use read_file instead.
|
|  remove_option(self, section, option)
|      Remove an option.
|
|  remove_section(self, section)
|      Remove a file section.
|
|  sections(self)
|      Return a list of section names, excluding [DEFAULT]
|
|  write(self, fp, space_around_delimiters=True)
|      Write an .ini-format representation of the configuration state.
|
|  clear(self)
|      D.clear() -> None.  Remove all items from D.
|
|  pop(self, key, default=<object object at 0x0000000002F42040>)
|      D.pop(k[,d]) -> v, remove specified key and return the corresponding value.
|      If key is not found, d is returned if given, otherwise KeyError is raised.
|
|  setdefault(self, key, default=None)
|      D.setdefault(k[,d]) -> D.get(k,d), also set D[k]=d if k not in D
|
|  update(*args, **kwds)
|      D.update([E, ]**F) -> None.  Update D from mapping/iterable E and F.
|      If E present and has a .keys() method, does:     for k in E: D[k] = E[k]
|      If E present and lacks .keys() method, does:     for (k, v) in E: D[k] = v
|      In either case, this is followed by: for k, v in F.items(): D[k] = v
|
|  keys(self)
|      D.keys() -> a set-like object providing a view on D's keys
|
|  values(self)
|      D.values() -> an object providing a view on D's values
