如何在tqdm pandas中添加描述？

Question

我希望在tqdm pandas进度条的前面或后面添加一个小描述，类似于以下内容：

import numpy as np
import pandas as pd
from tqdm.auto import tqdm; tqdm.pandas()

a = pd.Series(np.arange(100))

squares = a.progress_map(lambda x: x**2) #this one works
cubes = a.progress_map(lambda x: x**3) #this one works

squares = a.progress_map(lambda x: x**2, desc = 'Computing squares...') #this one doesn't work
cubes = a.progress_map(lambda x: x**3, desc = 'Computing cubes...') #this one doesn't work

那么，我该如何添加进度条的描述呢？

Answer 1

也许是这样的：

import numpy as np
import pandas as pd
from tqdm.auto import tqdm

a = pd.Series(np.arange(100))

tqdm.pandas(desc='Computing squares')
squares = a.progress_map(lambda x: x**2)

tqdm.pandas(desc='Computing cubes')
cubes = a.progress_map(lambda x: x**3)

Output:

Computing squares: 100%|██████████| 100/100 [00:00<00:00, 37766.11it/s]
Computing cubes: 100%|██████████| 100/100 [00:00<00:00, 30211.80it/s]

这个会起作用，但是你会收到一个警告：

squares = a.progress_map(lambda x: x**2,print('Computing squares...') )
