Python Programming/Progress Bars
Progress bars in Python are abundant. There are several well-known packages for progress bars out there.
External Progress Bars edit
Some of the top bars are from the progress and the tqdm library.
Progress edit
| Easy to use progress bars | |
| PyPi Link | https://pypi.python.org/pypi/progress |
|---|---|
| Pip command | pip install progress |
| Import command | import progress.bar or import progress.spinner |
The progress module provides 7 different progress bars to use. They are:
- Bar
- ChargingBar
- FillingSquaresBar
- FillingCirclesBar
- IncrementalBar
- PixelBar
- ShadyBar
The module also provides 6 spinners. These do not have a finish. They are:
- Spinner
- PieSpinner
- MoonSpinner
- LineSpinner
- PixelSpinner
In order to access a bar/spinner, you run progress.a.b, where a is the type of indicator you want (bar or spinner) and b is the name of the bar/spinner. Furthermore, you have to import the module as progress.a or else it cannot see the bar/spinner.
Example code edit
import progress.bar
import time
b = progress.bar.Bar('Waiting', max = 100)
for i in range(100):
b.next()
time.sleep(0.1)
b.finish()
We can also make it an iterator so we can put it into a for loop.
from __future__ import print_function
import progress.bar
import time
b = progress.bar.Bar('Printing', max = 26)
letters = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 'q', 'r', 's', 't', 'u', 'v', 'w', 'x', 'y', 'z']
for letter in b.iter(letters):
print(letter)
time.sleep(0.1)
b.finish()
Tqdm edit
| Fast, Extensible Progress Meter | |
| PyPi Link | https://pypi.python.org/pypi/tqdm |
|---|---|
| Pip command | pip install tqdm |
The tqdm module relies off of one main class, the tqdm class. It has a GUI version, and a jupyter notebook-compatible version, and one for pandas. It will run as an iterator, a callable bar, and an action in a with statement.
Basic Code edit
from tqdm import tqdm
adder = 1
sum = 0
for i in tqdm(range(100)):
sum += adder
