Pandas创建列名称子集的列表，但只有一个列名除外

column_names = df.columns.tolist()

subset = [col for col in column_names if col != 'exclude_column_name']

import pandas as pd

# 创建一个示例DataFrame
data = {'A': [1, 2, 3],
        'B': [4, 5, 6],
        'C': [7, 8, 9]}
df = pd.DataFrame(data)

# 获取所有列名称
column_names = df.columns.tolist()

# 创建列名称子集的列表，但排除一个特定的列名
subset = [col for col in column_names if col != 'C']

print(subset)

['A', 'B']
