Usage

Use probar or bar for different situations:

probar:

from pyprobar import bar, probar
import time

for idx, x in probar(range(1234), enum=True): 
    time.sleep(0.02)

>>> 18.31%|█████>>>>>                  | 0:00:20|0:00:25  ETC: 05-20 19:00:39

Or used in List comprehension:

res = [i for i in probar(range(10))]
print(res)

>>> 100.00%|███████████████████████████| 0:00:00|0:00:00 ETC: 05-20 12:14:33
>>> [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

bar:

import numpy as np
N = 1024
a = np.linspace(2, 5, N)
for idx, i in enumerate(a):
    time.sleep(0.01)
    bar(idx, N)

>>> 100.00% |███████████████████████████| 0:00:00|0:00:10  ETC: 05-20 20:33:34 

You can set your own progress bar by using the parameters symbol_1 and symbol_2 :

for i in probar(range(1234), symbol_2="o"):
    time.sleep(0.01)

>>> 23.10%|██████ooooooooooooooooooo    | 0:00:10|0:00:14  ETC: 05-20 17:29:57

Tip: Searchcharmap in win10 start menu, you can find a lot of interesting characters.

Supports progress bars in different colors:

for idx, i in enumerate(a):
    bar(idx, N, color='1') # `color` options: '1','2','3','4','5','0','update_random'
    time.sleep(0.01)

Of course, you can also add text or variables to the progress bar:

for idx, i in enumerate(a):
    text = f"what you want see is {x}"
    bar(idx, N, text=text)

<img src=picture/text.gif />

multi-line text :

for idx, i in enumerate(a):
    text = f"{v1}, frame:{idx}\n"
    bar(idx, N, text=text)

Specify the time zone:

for i in enumerate(a):
    bar(idx, N, time_zone="Asia/Shanghai")

print RGB color string:

from pyprobar.styleString import rgb_str
    text = rgb_str("I'm green!", RGB_fore=[0,255,0])
    print(text)

<img src=picture/rgb_str.jpg />
