如何删除Pandas中包含零值的列？

import pandas as pd

# 创建示例数据框
data = {'A': [1, 2, 3, 4],
        'B': [0, 0, 0, 0],
        'C': [1, 0, 3, 0],
        'D': [0, 0, 0, 0]}
df = pd.DataFrame(data)

# 获取不包含零值的列名称
cols_to_keep = [col for col in df.columns if not df[col].isin([0]).any()]

# 删除包含零值的列
df = df[cols_to_keep]

print(df)

   A  C
0  1  1
1  2  0
2  3  3
3  4  0
