with tqdm(total=100) as pbar: with open('large_file.txt', 'r') as file: for line in file: # 对每行进行处理的代码 pbar.update(1) 这个例子中,total=100预设了文件的总行数(或预估的处理次数),并通过pbar.update(1)来逐行更新进度条。 嵌套进度条 tqdm支持嵌套进度条,这在处理具有多层循环的...

在这个示例中,我们使用with open('tqdm_output.txt', 'w') as f:来打开一个文件,并将文件对象f传递给tqdm的file参数。这样,tqdm的所有输出都将被写入到tqdm_output.txt文件中,而不是显示在控制台上。同时,使用with语句可以确保文件在循环结束后被正确关闭。 请注意,这种方法会使得tqdm的进度条不在控制台上显...
