尝试在DataFrame中查找空列并将其提取为Python中的列表？

import pandas as pd
import numpy as np

df = pd.DataFrame({'A': [1, 2, np.nan, 4],
                   'B': [np.nan, 2, 3, 4],
                   'C': [1, 2, 3, 4]})

empty_columns = df.columns[df.isnull().any()].tolist()

print(empty_columns)

import pandas as pd
import numpy as np

df = pd.DataFrame({'A': [1, 2, np.nan, 4],
                   'B': [np.nan, 2, 3, 4],
                   'C': [1, 2, 3, 4]})

empty_columns = df.columns[df.isnull().any()].tolist()
print(empty_columns)
