Python控制台显示动态进度条

from tqdm import tqdm# 创建一个进度条progress_bar = tqdm(total=100)# 更新进度条for i in range(100):    progress_bar.update()# 结束进度条progress_bar.close()

from progressbar2 import ProgressBar# 创建一个进度条progress_bar = ProgressBar(max_value=100)# 更新进度条for i in range(100):    progress_bar.update(i)

import sys# 总任务数total_tasks = 100# 完成任务数completed_tasks = 0# 进度条长度bar_length = 20# 打印进度条while completed_tasks < total_tasks:    percent_complete = completed_tasks / total_tasks    filled_chars = int(bar_length * percent_complete)    empty_chars = bar_length - filled_chars    progress_bar = '[' + '=' * filled_chars + ' ' * empty_chars + ']'    sys.stdout.write(f"{progress_bar} - {percent_complete:.2%}")    sys.stdout.flush()    completed_tasks += 1
