Python如何实现进度条功能？

本文共计181个文字，预计阅读时间需要1分钟。

使用pip安装tqdm库，并演示其基本使用：

pythonpip install tqdmfrom tqdm import tqdmimport time

使用tqdm进行简单的进度条展示for char in tqdm(['a', 'b', 'c', 'd']): time.sleep(0.2)for i in tqdm(range(4)): time.sleep(0.2)for i in tqdm(range(10)): time.sleep(0.2)

pip install tqdm

from tqdm import tqdm,trange
import time

for char in tqdm(['a','b','c','d']):
time.sleep(0.2)
for i in trange(4):
time.sleep(0.2)

for i in trange(10):
time.sleep(0.2)

pbar = tqdm(["a", "b", "c", "d"])
for char in pbar:
time.sleep(0.8)
pbar.set_description("Processing %s" % char)

with tqdm(total=100) as pbar:
for i in range(10):
time.sleep(1)
pbar.update(10)
