Python3中的StringIO

我使用的是Python 3.2.1,我无法导入StringIO模块.我用
io.StringIO它可以工作,但我不能像numpy的genfromtxt这样使用它：

x="1 3\n 4.5 8"        
numpy.genfromtxt(io.StringIO(x))

我收到以下错误：

TypeError: Can't convert 'bytes' object to str implicitly  

当我写入导入StringIO时,它说

ImportError: No module named 'StringIO'

解决方法:

when i write import StringIO it says there is no such module.

从What’s New In Python 3.0开始：

The StringIO and cStringIO modules are gone. Instead, import the io
module and use io.StringIO or io.BytesIO for text and data
respectively.

.

修复一些Python 2代码的一种可能有用的方法也适用于Python 3(需要注意的话)：

try:
    from StringIO import StringIO
except ImportError:
    from io import StringIO

Note: This example may be tangential to the main issue of the question and is included only as something to consider when generically addressing the missing StringIO module. For a more direct solution the the message TypeError: Can't convert 'bytes' object to str implicitly, see 07001.
