... AstroAsciiData is a Python module to handle ASCII tables. ... The idea to develop this Python module emerged from the fact that ASCII tables continue to be one of the most popular and widely used data exchange formats in astronomy and probably science in general. ... To load this ASCII table, go into Python, load the AstroAsciiData module and read in the table with: . ... demo = asciidata.open('webexa.txt') . ... Users who only want to work with ASCII tables neeed no further python modules. ...
