Statusbar for Python for/while loops with danpy.sb

This helpful statusbar can be used with for/while loops to keep track of how much time has elapsed as well as how much time remains. Simply place inside the loop (after initializing the statusbar -- dsb) and update with the current timestep (i). A title can be added to the statusbar to keep track of individual function/loops and it is recommended that any function that runs a loop uses arbitrary_function_name.__name__ to automatically assign an appropriate title.

Initialize statusbar before running a for/while loop.

from danpy.sb import *
from time import sleep

statusbar = dsb()
number_of_loops = 10
for i in range(number_of_loops):
  sleep(0.5)
  statusbar.update(i,number_of_loops,title="Test Loop")

It is useful to either reset the statusbar instance. However, loops run in succession will automatically reset if the loops are of the same size.

from danpy.sb import *
from time import sleep

statusbar = dsb()
number_of_inside_loops = 10
number_of_outside_loops = 3
for j in range(number_of_outside_loops):
  for i in range(number_of_inside_loops):
    sleep(0.5)
    statusbar.update(i,number_of_inside_loops,title="Testing Loop-D-Loops")

number_of_additional_loops = 10
for i in range(number_of_additional_loops):
  sleep(0.5)
  statusbar.update(i,number_of_additional_loops,title="Test Another Loop")

Resetting Statusbar

from danpy.sb import *
from time import sleep

statusbar = dsb()
number_of_loops = 10
for i in range(number_of_loops):
  sleep(0.5)
  statusbar.update(i,number_of_loops,title="Testing One Loop")

statusbar.reset()
a_different_number_of_loops = 20
for i in range(a_different_number_of_loops):
  sleep(0.5)
  statusbar.update(i,a_different_number_of_loops,title="Test A Different Loop")

Using while Loops

If using a while loop, the statusbar will still update, but depending on the nature of the code in the loop, the extrapolation to determine time remaining may be off.

from danpy.sb import *
from time import sleep

statusbar = dsb()
count = 0
number_of_loops = 10
while count<number_of_loops:
  sleep(0.5)
  statusbar.update(count,number_of_loops,Title="Testing One Loop")
  count+=1

Only compatible with while loops that utilize a count metric where the loop continues while count<number_of_loops. The "<" ensures that the statusbar terminates at 100%. If you use "<=" then the input to the statusbar will be statusbar.update(i,number_of_loops+1,**kwargs).
