如何在 Python 中为 for i in range(...) 循环添加进度条

你可以使用 tqdm 库轻松地为 Python for i in range(...) 循环添加进度条：

只需

tqdm_example.py

from tqdm import tqdm

from tqdm import tqdm

放在脚本顶部，然后用 tqdm(...) 包围 range(...)。例如，

tqdm_simple_loop.py

mysum = 0
for i in range(50):
    sum += i

mysum = 0
for i in range(50):
    sum += i

变为

tqdm_progress_example.py

mysum = 0
for i in tqdm(range(50)):
    mysum += i

mysum = 0
for i in tqdm(range(50)):
    mysum += i
