PyPrind

The PyPrind (Python Progress Indicator) module lets you visualize the progress of a programming task in Python via a progress bar or a percentage indicator.

Installation

You can use the following command to install PyPrind:
pip install pyprind or
easy_install pyprind

Or you download the package manually, unzip it, and install it from the package folder via:

python setup.py install or python3 setup.py install

Documentation

PyPrind consists of two class objects that can visualize the progress of a computation on the output screen.
Progress bars are visualized via a ProgBar() object, and alternatively, the progress can be shown as an percentage via the ProgPercent() object.

The general usage of ProgBar() and ProgPercent() consists of three steps:

1. initialize a new ProgBar() or ProgPercent() object with the number of iterations of the computation that is to be performed
   
2. update the ProgBar() or ProgPercent() object for each iteration via the .update()method
   
3. complete the progress visualization via the .finish() method after the computation is completed

n = 10000000
my_prbar = pyprind.ProgBar(n)      # 1) initialization with number of iterations
for i in range(n):  
    # do some computation
    my_prbar.update()           # 2) update the progress visualization
my_prbar.finish()               # 3) complete the progress visualization

### Optional parameters :
##### Setting the width of the progress bar

my_prog = pyrpind.ProgBar(width=70) # default = 50

##### Set whether CPU time should be reported or not The optional cpu_time parameter can be set for both ProgBar() and ProgPercent() objects.
E.g.,
my_prbar.finish(cpu_time=False) # (default = True)

Examples

The following examples shall illustrate the typical usage of the PyPrind package.
An visualization can be viewed on YouTube: http://youtu.be/gjj5K8OWo7U

### Example - Progress Bar

import pyprind

n = 10000000
my_prbar = pyprind.ProgBar(n)
for i in range(n):
    # do some computation
    my_prbar.update()
my_prbar.finish()

Example - Percentage Indicator

import pyprind

n = 1000000
my_perc = pyprind.ProgPercent(n)
for i in range(n):
    # do some computation
    my_perc.update()
my_perc.finish() 

Screen Output
