astropy.io.ascii Documentation

An extensible ASCII table reader and writer for Python 2 and 3.

The astropy.io.ascii packge can read and write a wide range of ASCII table formats via built-in Extension Reader Classes:

• Basic: basic table with customizable delimiters and header configurations
• Cds: CDS format table (also Vizier and ApJ machine readable tables)
• CommentedHeader: column names given in a line that begins with the comment character
• Daophot: table from the IRAF DAOphot package
• FixedWidth: table with fixed-width columns (Fixed-width Gallery)
• Ipac: IPAC format table
• Latex, AASTex: LaTeX tables (plain and AASTex)
• Memory: table already in memory (list of lists, dict of lists, etc)
• NoHeader: basic table with no header where columns are auto-named
• Rdb: tab-separated values with an extra line after the column definition line
• Tab: tab-separated values

The astropy.io.ascii package is built on a modular and extensible class structure with independent Base class elements so that new formats can be easily accomodated.
