non-str postfix (lists/dicts/objects)

[casperdcl]

• Allow for postfix to be a list now, thus allowing for a fully customisable bar (fixes Allow to customize every part of the message string #382)
  • documentation
  • unit tests
• misc doc updates

from tqdm import tqdm
from time import sleep


with tqdm(total=10, bar_format="{postfix[0]} {postfix[1]:>8.2g}",
          postfix=["Batch", 0]) as t:
    for i in range(10):
        sleep(0.1)
        t.postfix[1] = i / 2
        t.update()
