如何在 python 中以非常慢的循环显示状态

Question

我想在 python 代码中以非常慢的循环每秒显示状态，例如

for i in range(100):
    sleep(1000000) # think there is a very slow job

    # I want to show status in console every second
    # to know if the job stop or not

output 图像是，例如

$ python somejob.py
> 2022-09-02 13:04:10 | Status: running... 

并且 output 每秒更新一次，例如

$ python somejob.py
> 2022-09-02 13:04:11 | Status: running... 

$ python somejob.py
> 2022-09-02 13:04:12 | Status: running... 

$ python somejob.py
> 2022-09-02 13:04:13 | Status: running... 

任何想法都会有所帮助。 谢谢！！！

Answer 1

我认为您正在寻找的类似于 tqdm 库： github repo

例如

from tqdm import tqdm
for i in tqdm(range(1000)):
    continue # do something complex here

Answer 2

您可以使用丰富的模块来显示进度条：

import time
from rich.progress import track

for i in track(range(100)):
    time.sleep(0.5)

这是运行中的屏幕截图：
