A Text Table Writer/Printer for Python

Question

TL;DR -> Is there a table writing module on PyPi (I\'ve failed to find any) that takes in lists as parameters and makes a table out of those

Answer 1

I’m just going to throw a solution from me in which I’ve actually written last week just to test something out. It currently right-aligns everything but it would be simple enough to add some alignment parameters or something.

def printTable (tbl, borderHorizontal = '-', borderVertical = '|', borderCross = '+'):
    cols = [list(x) for x in zip(*tbl)]
    lengths = [max(map(len, map(str, col))) for col in cols]
    f = borderVertical + borderVertical.join(' {:>%d} ' % l for l in lengths) + borderVertical
    s = borderCross + borderCross.join(borderHorizontal * (l+2) for l in lengths) + borderCross

    print(s)
    for row in tbl:
        print(f.format(*row))
        print(s)

Example:

>>> x = [['Length', 'Time(ms)'], [0, 0], [250, 6], [500, 21], [750, 50], [1000, 87], [1250, 135], [1500, 196], [1750, 269], [2000, 351]]
>>> printTable(x)
+--------+----------+
| Length | Time(ms) |
+--------+----------+
|      0 |        0 |
+--------+----------+
|    250 |        6 |
+--------+----------+
|    500 |       21 |
+--------+----------+
|    750 |       50 |
+--------+----------+
|   1000 |       87 |
+--------+----------+
|   1250 |      135 |
+--------+----------+
|   1500 |      196 |
+--------+----------+
|   1750 |      269 |
+--------+----------+
|   2000 |      351 |
+--------+----------+
