Tqdm 是一个快速，可扩展的Python进度条，可以在 Python 长循环中添加一个进度提示信息，用户只需要封装任意的迭代器 tqdm(iterator)。
使用pip就可以安装。
使用方法一: tqdm
tqdm(list)方法可以传入任意一种list,比如数组
from tqdm import tqdm
for i in tqdm(range(1000)):
#do something
pass
- 1
- 2
- 3
- 4
- 5
或者string的数组
for char in tqdm(["a", "b", "c", "d"]):
#do something
pass
- 1
- 2
- 3
使用方法二: trange
trange(i) 是 tqdm(range(i)) 的简单写法
from tqdm import trange
for i in trange(100):
#do something
pass
- 1
- 2
- 3
- 4
使用方法三: 手动方法
在for循环外部初始化tqdm,可以打印其他信息
bar = tqdm(["a", "b", "c", "d"])
for char in pbar:
pbar.set_description("Processing %s" % char)
- 1
- 2
- 3
