I have written a Python 2/3 compatible script that parses data and builds the output as a list of CSV strings. The script provides an option to write the data to a CSV file, or display to stdout. While I could easily iterate through the list and replace "," with "\t" when displaying to stdout, the items are of arbitrary length, and thusly don't line up in a nice format due to variances in tabs. I have done quite a bit of research, and believe that string format options may accomplish what I'm after. That said, I can't seem to find an example that helps me get the syntax correct.
I would prefer not to use an external library. I am aware that there are many options available if I went that route, but I want the script to be as compatible and simple as possible.
Here is an example:
Any suggestions are much appreciated.
import csv from StringIO import StringIO rows = list(csv.reader(StringIO( '''value1,somevalue2,value3,reallylongvalue4,value5,superlongvalue6 value1,value2,reallylongvalue3,value4,value5,somevalue6'''))) widths = [max(len(row[i]) for row in rows) for i in range(len(rows))] for row in rows: print(' | '.join(cell.ljust(width) for cell, width in zip(row, widths)))
value1 | somevalue2 | value3 | reallylongvalue4 | value5 | superlongvalue6 value1 | value2 | reallylongvalue3 | value4 | value5 | somevalue6
