In Python, you can utilize the tqdm library to print progress bars. The tqdm library offers a ProgressBar class that automatically updates the progress bar based on the iteration progress.

Firstly, make sure you have installed the tqdm library. You can install it using the following command:

pip install tqdm

Next, you can use the tqdm library to print a progress bar in the following way:

from tqdm import tqdm

# 创建一个迭代对象
my_list = range(1000)

# 使用tqdm进行迭代，并自动更新进度条
for item in tqdm(my_list):
    # 在这里添加你的代码
    pass

The above code will create an iterator with 1000 elements and print a progress bar using the tqdm library. You can add your code to be executed within the for loop.

The tqdm library also provides additional features such as setting the description of the progress bar, customizing the style of the progress bar, and limiting the maximum width of the progress bar. Refer to the tqdm library documentation for more detailed information.
