A Python Progressbar library to provide visual (yet text based) progress to long running operations.
The package can be installed through pip (this is the recommended method):
pip install progressbar2
Or if pip is not available, easy_install should work as well:
Or download the latest release from Pypi (https://pypi.python.org/pypi/progressbar2) or Github.
Note that the releases on Pypi are signed with my GPG key (https://pgp.mit.edu/pks/lookup?op=vindex&search=0xE81444E9CE1F695D) and can be checked using GPG:
gpg –verify progressbar2-<version>.tar.gz.asc progressbar2-<version>.tar.gz
A text progress bar is typically used to display the progress of a long running operation, providing a visual cue that processing is underway.
The ProgressBar class manages the current progress, and the format of the line is given by a number of widgets. A widget is an object that may display differently depending on the state of the progress bar. There are many types of widgets:
The progressbar module is very easy to use, yet very powerful. It will also automatically enable features like auto-resizing when the system supports it.
Due to limitations in both the IDLE shell and the Jetbrains (Pycharm) shells this progressbar cannot function properly within those.
There are many ways to use Python Progressbar, you can see a few basic examples here but there are many more in the examples file.
import time import progressbar bar = progressbar.ProgressBar() for i in bar(range(100)): time.sleep(0.02)
Progressbars with logging require stderr redirection _before_ the StreamHandler is initialized. To make sure the stderr stream has been redirected on time make sure to call progressbar.streams.wrap_stderr() before you initialize the logger.
One option to force early initialization is by using the WRAP_STDERR environment variable, on Linux/Unix systems this can be done through:
# WRAP_STDERR=true python your_script.py
In most cases the following will work as well, as long as you initialize the StreamHandler after the wrapping has taken place.
import time import logging import progressbar progressbar.streams.wrap_stderr() logging.basicConfig() bar = progressbar.ProgressBar() for i in bar(range(10)): logging.error('Got %d', i) time.sleep(0.2)
import time import progressbar with progressbar.ProgressBar(max_value=10) as bar: for i in range(10): time.sleep(0.1) bar.update(i)
import time import progressbar bar = progressbar.ProgressBar(redirect_stdout=True) for i in range(100): print 'Some text', i time.sleep(0.1) bar.update(i)
import time import progressbar bar = progressbar.ProgressBar(max_value=progressbar.UnknownLength) for i in range(20): time.sleep(0.1) bar.update(i)
import time import progressbar bar = progressbar.ProgressBar(widgets=[ ' [', progressbar.Timer(), '] ', progressbar.Bar(), ' (', progressbar.ETA(), ') ', ]) for i in bar(range(20)): time.sleep(0.1)
