Question

调试时，我经常会进入IPython shell进行交互式代码测试。但是，这也会导致python版本，日期和帮助指令的大型信息转储到stdout。如何抑制此信息，以免模糊故意调试消息？

x = get_important_data()
print 'important info! right here! The data is in variable "x"'
import IPython
IPython.embed()

此代码提供如下输出......

important info! right here! The data is in variable "x"
Python 2.7.11 |Anaconda 2.4.0 (x86_64)| (default, Dec  6 2015, 18:57:58)

你可以这样做：

  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/ctypes/__init__.py", line 365, in __init__
    self._handle = _dlopen(self._name, mode)
OSError: dlopen(libportmidi.dylib, 6): image not found

将IPython.embed(banner1="")设置为空字符串会使启动消息消失。它实际上不会删除消息，但会用空字符串替换它们。

您还可以使用banner1，banner1和banner2参数添加有用的消息：

exit_msg

如果您需要从命令行启动IPython实例，可以执行以下操作：

IPython.embed(
    banner1="Entering Debug Mode", 
    banner2="Here's another helpful message",
    exit_msg="Exiting the debug mode!"
)

如何禁止IPython启动消息？
