我有一个由数百列组成的数据框架，我需要看到所有的列名。

我做了什么:

In[37]:
data_all2.columns

输出结果为:

Out[37]:
Index(['customer_id', 'incoming', 'outgoing', 'awan', 'bank', 'family', 'food',
       'government', 'internet', 'isipulsa',
       ...
       'overdue_3months_feature78', 'overdue_3months_feature79',
       'overdue_3months_feature80', 'overdue_3months_feature81',
       'overdue_3months_feature82', 'overdue_3months_feature83',
       'overdue_3months_feature84', 'overdue_3months_feature85',
       'overdue_3months_feature86', 'loan_overdue_3months_total_y'],
      dtype='object', length=102)

我如何显示所有列，而不是一个截断列表?
