如何在python pandas数据帧中拆分逗号，然后删除逗号

import pandas as pd

# 创建一个包含逗号的数据帧
df = pd.DataFrame({'column': ['1,2,3', '4,5,6', '7,8,9']})

# 拆分逗号并创建新的列
df['new_column'] = df['column'].str.split(',')

# 删除逗号
df['new_column'] = df['new_column'].apply(lambda x: [i.replace(',', '') for i in x])

# 打印结果
print(df)

   column new_column
0   1,2,3  [1, 2, 3]
1   4,5,6  [4, 5, 6]
2   7,8,9  [7, 8, 9]
