在 pandas 的新版本 0.13.0 中，数据帧 df 使用以下命令打印在一长串数字中
df
or
print df
而不是像以前那样进行概述，现在只能使用
df.info()
是否可以更改默认的“df”或“print df”命令以显示：
In [12]: df.info()
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 4319 entries, 2010-02-18 00:00:00 to 2010-03-13 23:15:00
Data columns (total 2 columns):
QInt 4319 non-null values
QHea 4319 non-null values
dtypes: float32(2)
再次代替：
In [11]: df
Out[11]:
QInt QHea

[4319 rows x 2 columns]
Set
pd.options.display.large_repr = 'info'
从 v.0.13 开始，默认值为“截断”。
In [93]: df = pd.DataFrame(np.arange(4319*2).reshape(4319,2))
In [94]: pd.options.display.large_repr = 'info'
In [95]: df
Out[95]:
<class 'pandas.core.frame.DataFrame'>
Int64Index: 4319 entries, 0 to 4318
Data columns (total 2 columns):
0 4319 non-null int32
1 4319 non-null int32
dtypes: int32(2)
我通过搜索字符串找到了这个'info()'在输出中：
In [65]: pd.set_option?
要使其成为交互式会话的默认行为：
如果您还没有设置，请定义环境变量Python启动 http://docs.python.org/2/using/cmdline.html#envvar-PYTHONSTARTUP类似的东西/home/user/bin/startup.py
然后编辑/创建/home/user/bin/startup.py包含类似的东西
import pandas as pd
pd.options.display.large_repr = 'info'
现在，每当您启动交互式 Python 会话时，startup.py文件将被执行，您将可以通过以下方式访问 pandaspd变量，以及large_repr默认为'info'.
