我正在尝试运行一个脚本,该脚本试图通过 puppet 管理在 centos7 系统上安装模块。我想为运行脚本时发生的安装实现一个进度条。我正在使用 tqdm 模块来执行此操作。这是我如何实现模块的快照:
from tqdm import tqdm
for i in tqdm(commands):
res = run_apply(i)
这里的 run_apply() 是实际处理运行和应用 puppet 配置的函数。
到目前为止一切顺利,我得到了一个进度条,但是当执行消息写入控制台时,它会一直向下移动控制台。但是,我需要进度条在控制台底部保持不变并动态更新,而运行消息不会干扰进度条。我希望控制台上的执行相关消息按照他们的意愿继续,但进度条应该从执行开始到结束一直停留在底部。
以下是我所看到的:
