By default, section names are case sensitive but keys are not [1]_. Leading and trailing whitespace is removed from keys and values. Values can be omitted if the parser is configured to allow it [1]_, in which case the key/value delimiter may also be left out. Values can also span multiple lines, as long as they are indented deeper than the first line of the value. Depending on the parser's mode, blank lines may be treated as parts of multiline values or ignored.\n\nBy default, a valid section name can be any string that does not contain '\\\\n'. To change this, see ConfigParser.SECTCRE.\n\nThe first section name may be omitted if the parser is configured to allow an unnamed top level section with allow_unnamed_section=True. In this case, the keys/values may be retrieved by UNNAMED_SECTION as in config[UNNAMED_SECTION].\n\nConfiguration files may include comments, prefixed by specific characters (# and ; by default [1]_). Comments may appear on their own on an otherwise empty line, possibly indented. [1]_\n\nBounded code example (external data; do not execute automatically):\n```ini\n[Simple Values]\nkey=value\nspaces in keys=allowed\nspaces in values=allowed as well\nspaces around the delimiter = obviously\nyou can also use : to delimit keys from values\n\n[All Values Are Strings]\nvalues like this: 1000000\nor this: 3.14159265359\nare they treated as numbers? : no\nintegers, floats and booleans are held as: strings\ncan use the API to get converted values directly: true\n\n[Multiline Values]\nchorus: I'm a lumberjack, and I'm okay\nI sleep all night and I work all day\n\n[No Values]\nkey_without_value\nempty string value here =\n\n[You can use comments]\n# like this\n; or this\n\n# By default only in an empty line.\n# Inline comments can be harmful because they prevent users\n# from using the delimiting characters as parts of values.\n# That being said, this can be customized.\n\n[Sections Can Be Indented]\ncan_values_be_as_well = True\ndoes_that_mean_anything_special = False\npurpose = formatting\n```\n\nAttribution: Adapted from Python Documentation under PSF-2.0.
