Python--tqdm进度条显示进度

安装tqdm库：

[code]pip install tqdm

一，显示进度条

[code]import tqdm
for i in tqdm(range(100)):
pass

100%|██████████| 100/100 [00:00<?, ?it/s]
Process finished with exit code 0

二，进度条跑起来

[code]import time
import tqdm
for i in tqdm(range(1000)):
time.sleep(0.0001)

100%|██████████| 1000/1000 [00:01<00:00, 521.68it/s]
Process finished with exit code 0

 三，手动更新进度条

[code]import tqdm
bar = tqdm(total=10000000000)
for i in range(100000000):
value = int(i * 0.000001 + 0.5) * 2
bar.update(value) #迭代值value不超出total

100%|██████████| 100000000/100000000 [00:00<00:00, 105322890.20it/s]
Process finished with exit code 0
