Python module to display a nice loading bar in a terminal window.

Install

Or:

Getting Started

There are 3 different loading bar:

1. Standard loading bar
2. Loading bar with size loaded, speed and remaining time
3. Loading bar with infos above plus a custom message (usefull to display a verbose loading bar)

Option 1

Standard loading bar without any other infos.

import loading
total_file_size = 1000
# Create a loading bar object with total_file_size in bytes
lb = loadingbar.LoadingBar(total_file_size)
# For every piece of file
for chunk in file:
  # Update the loading bar with the len of new data
  lg.update(len(chunk))
# When finished, display a 100% loading bar
lg.done()

Option 2

Standard loading bar with infos such as size downloaded, speed, eta.

import loading
total_file_size = 1000
lb = loadingbar.InfoLoadingBar(total_file_size)
# Run as above

Option 3

This special InternetLoadingBar smooth the speed calculation by taking the overall average time rather than a instant speed.

import loading
total_file_size = 1000
lb = loadingbar.InternetLoadingBar(total_file_size)
# Run as above

Option 4

Loading bar that displays a message, like for example the filename that it is downloaded. Two options:

• loadingbar.MessageLoadingBar
• loadingbar.VerboseLoadingBar

import loading
total_file_size = 1000
lb = loadingbar.VerboseLoadingBar(total_file_size)
# For every piece of file
for chunk in file:
  # Update the loading bar with the len of new data
  lg.update(len(chunk), "Message to be displayed, such as filename, etc.")
# When finished, display a 100% loading bar
lg.done()

Option 5

Add a percentage after the loading bar.

• loadingbar.PercentageLoadingBar(tot_size)
  

• loadingbar.PercentageInfoLoadingBar(tot_size)
  

Option 6

Add a percentage after the loading bar.

• loadingbar.PercentageBeforeLoadingBar(tot_size)
  

• loadingbar.PercentageBeforeLoadingBarAndInfo(tot_size)
  

Customization

If a new and custom loading bar is needed, you can implement a new one by inheriting from the LoadingBar class or the abstract class ILoadingBar.
See loading > loading_bar.py for examples.
