How is the Progressbar used in Python?

In Python, you can use the progressbar library to create a progress bar. This library offers a simple way to display the progress of a loop or task.

Firstly, the progressbar library needs to be installed. This can be done by using the following command:

pip install progressbar2

Next, you can follow these steps to use the progressbar library:

1. a bar showing the progress of a task

import progressbar

1. Create a progress bar object.

progress = progressbar.ProgressBar()

1. loading bar
2. make updates

for i in progress(range(100)):
    # 执行循环或任务的代码

The progress bar will automatically update at the completion of each loop or task.

Here is a complete example:

import progressbar

progress = progressbar.ProgressBar()

for i in progress(range(100)):
    # 执行循环或任务的代码
    # 可以在此处添加任何你需要的代码
    pass

This way, a progress bar can be displayed during a loop or task execution, and its status will be updated in real-time.
