I needed to pretty print an ASCII table for visually comparing some data, and
later sharing that data via email. One solution was PrettyTable. Here, we add
one row at a time.
from prettytable import PrettyTable
import random
pt.field_names = ["A", "B"]
for i in range(3):
pt.add_row([random.uniform(0,1), random.uniform(0,1)])
print(pt)+---------------------+--------------------+
| A | B |
+---------------------+--------------------+
| 0.08361361205835316 | 0.9656697789827289 |
| 0.22408201780859394 | 0.7433186247709901 |
| 0.30245953986183527 | 0.2747904360016633 |
+---------------------+--------------------+
We can also add multiple rows at once.
from prettytable import PrettyTable
import random
pt.field_names = ["A", "B"]
data = [[random.uniform(0,1) for _ in range(2)] for _ in range(3)]
pt.add_rows(data)
print(pt)+---------------------+---------------------+
| A | B |
+---------------------+---------------------+
| 0.12829427296035023 | 0.34039455384333606 |
| 0.16237986127000037 | 0.8656983724296935 |
| 0.10883190531646758 | 0.7514955800774817 |
