Thanks. That code is so simple and works. However, there are things to be considered. With the CSV format, cells in a row are separated by ',' and for some cells it writes "" around the cell content.
So, if the excel looks like CHR1 11,232,445 The output file looks like CHR1,"11,232,445" Is it possible to use <space> as the delimiting character and omit ""? I say that because, my java code which has to read the output file has to do some extra works (using space as delimiter is the default and much easier to work). I want a[0][0] = CHR a[0][1] = 11,232,445 And both are strings. Is that possible? Regards, Mahmood -- https://mail.python.org/mailman/listinfo/python-list
