删除dataframe中包含字符串的所有列

import pandas as pd

def delete_columns_with_string(df, string):
    columns_to_drop = []
    for column in df.columns:
        if string in column:
            columns_to_drop.append(column)
    
    df = df.drop(columns=columns_to_drop)
    return df

# 示例数据
data = {'Column1': [1, 2, 3], 'Column2': [4, 5, 6], 'Column3_String': ['a', 'b', 'c']}
df = pd.DataFrame(data)

# 删除包含字符串"String"的列
new_df = delete_columns_with_string(df, "String")

print(new_df)

   Column1  Column2
0        1        4
1        2        5
2        3        6
