By default this prints to standard output via sys.stdout. The ``option`` argument specifies what type of information to include. This can be a string, a function, or a list of strings or functions. Built-in options are: - ``attributes``: basic column meta data like ``dtype`` or ``format`` - ``stats``: basic statistics: minimum, mean, and maximum If a function is specified then that function will be called with the column as its single argument. The function must return an OrderedDict containing the information attributes. If a list is provided then the information attributes will be appended for each of the options, in order. Examples -------- >>> from astropy.table.table_helpers import simple_table >>> t = simple_table(size=2, kinds='if') >>> t['a'].unit = 'm' >>> t.info() name dtype unit ---- ------- ---- a int64 m b float64 >>> t.info('stats')
name mean std min max ---- ---- --- --- --- a 1.5 0.5 1 2 b 1.5 0.5 1 2 Parameters ---------- option : str, callable, list of (str or callable) Info option, defaults to 'attributes'. out : file-like, None Output destination, default is sys.stdout. If None then a Table with information attributes is returned Returns ------- info : `~astropy.table.Table` if out==None else None )Tabler z masked=Truezlength=< >N)outr)namesclasscss|]}t|VqdSN)type).0colr1lib/python3.9/site-packages/astropy/table/info.py `ztable_info..Zn_badZlengthZSUF)Z max_widthZ max_linesZ show_unitz css|]}|tjVqdSr)oslinesep)rZoutlinerrrrtr)tabler sysstdout __class____name__ZmaskedappendlenjoinlistcolumnsvaluesZcolnamesinfoset isinstanceZ ColumnClassnpallZdtypekindextendZpformat writelines) tbloptionrr Z descr_valsZoutlinesZcolsZinfosrr(Z uniq_typesnamerrrrs@2     $ &  rc@seZdZdddZeje_dS)rrr cCst|j||Sr)rZ_parent)selfr1rrrr__call__xszTableInfo.__call__N)rr )r! __module__ __qualname__r4r__doc__rrrrrws rc #sfdd}i}rd|D]F}t|jdr||r|jj||jj<fdd|jjD|j_qz,dVWr|D]\}}|||j_qzn$r|D]\}}|||j_q0dS)aContext manager to temporarily override individual column info.serialize_method dict values. The serialize_method attribute is an optional dict which might look like ``{'fits': 'jd1_jd2', 'ecsv': 'formatted_value', ..}``. ``serialize_method`` is a str or dict. If str then it the the value is the ``serialize_method`` that will be used for all formats. If dict then the key values can be either: - Column name. This has higher precedence than the second option of matching class. - Class (matches any column which is an instance of the class) This context manager is expected to be used only within ``Table.write``. It could have been a private method on Table but prefer not to add clutter to that class.
