def __getitem__(self, key: Union[str, List[str]]) -> Union[Table, Self]:
r"""
Return the (subset of) table(s) referenced by `key`.
The `key` can represent a single object name (e.g. "ACAF") or a list of object names ("ACAF;ACAG;AOUC")
or a pattern (e.g. "A*") or a list of sub-patterns (e.g. "A*;*_").
If the `key` represents a list of object names or of sub-patterns, each name or sub-pattern is separated
by a `separator` character which is either a whitespace ` `, or a comma `,`, or a semi-colon `;`, or a
tabulation `\t`, or a newline `\n`.
A (sub-)`pattern` is a list of characters representing a group of object names.
It includes some special characters which have a special meaning:
- `*` : any character sequence, even empty
- `?` : any character (one and only one)
- `@` : any alphanumerical char [A-Za-z0-9]
- `&` : any non alphanumerical char
- `|` : any alphanumeric character or none at the beginning and end of a string
- `!` : any non-alphanumeric character or none at the beginning and end of a string
- `\` : escape the next character
Note that the `key` can contain references to IODE lists which are prefixed with the symbol `$`.
Parameters
----------
key: str or list(str)
(the list of) name(s) of the table(s) to get.
The list of tables to get can be specified by a pattern or by a list of sub-patterns (e.g. "A*;*_").
Returns
-------
Single table or a subset of the database.
Examples

r"""
Update/add a (subset of) table(s) referenced by `key` from/to the Tables database.
The `key` can represent a single object name (e.g. "ACAF") or a list of object names ("ACAF;ACAG;AOUC")

Note that the `key` can contain references to IODE lists which are prefixed with the symbol `$`.
Parameters
----------
key: str or list(str)
(the list of) name(s) of the table(s) to update/add.
The list of tables to update/add can be specified by a pattern or by a list of sub-patterns
(e.g. "A*;*_").
value: int, Table, dict(str, ...) or Tables
If int, then it is interpreted as the number of columns to create a new empty table.
If Table, then it is used to update an existing table or to create a new table if it does not exist yet.

def print_to_file(self, filepath: Union[str, Path], names: Union[str, List[str]]=None, format: str=None, generalized_sample: str=None, nb_decimals: int=4):
"""
Print the list tables defined by `names` to the file `filepath` using the format `format`.
Argument `format` must be in the list:
- 'H' (HTML file)
- 'M' (MIF file)
- 'R' (RTF file)
- 'C' (CSV file)
If argument `format` is null (default), the *A2M* format will be used to print the output.
If the filename does not contain an extension, it is automatically added based on
the value of `format`.
If `names` is a string, it is considered as a *pattern* and the function will print
all tables matching the pattern. The following characters in *pattern* have a
special meaning:
- `*` : any character sequence, even empty
- `?` : any character (one and only one)
- `@` : any alphanumerical char [A-Za-z0-9]
- `&` : any non alphanumerical char
- `|` : any alphanumeric character or none at the beginning and end of a string
- `!` : any non-alphanumeric character or none at the beginning and end of a string
- `\` : escape the next character
If `names` is None, print all tables of the (subset of the) current database.
Parameters
----------
filepath: str or Path
path to the file to print.
If the filename does not contain an extension, it is automatically
added based on the value of the format argument.
names: str or list of str, optional
pattern or list of names of the tables to print.
If None, print all tables of the (subset of the) current database.
Defaults to None.
format: str, optional
format of the output file. Possible values are: 'H' (HTML file),
'M' (MIF file), 'R' (RTF file) or 'C' (CSV file).
Defaults to None meaning that the tables will be dumped in the *A2M* format.
generalized_sample: str
generalized sample to use for computing the tables.
Mandatory if `print_tables_as` is `PrintTablesAs.COMPUTED`.
nb_decimals: int, optional
number of decimals to use for computing the tables.
Only used if `print_tables_as` is `PrintTablesAs.COMPUTED`.
Defaults to 4.
