您可以将df.filter与regex一起使用来完成此操作。

import pandas as pd

# sample dataframe
df = pd.DataFrame({'foo': [1, 2, 3], 'bar': [4, 5, 6], 'ber': [7, 8, 9]})

# sample list of strings
mylist = ['oo', 'ba']

# join the list to a single string
matches = '|'.join(mylist)

# use regex to filter the columns based on the string
df_out = df.filter(regex=matches)
