Windows操作系统无法打开适用于Linux的文件名

Question

我正在Linux上开发一个小型Python应用程序，其中代码在系统Python3和Anaconda Python3解释器上运行良好。但是，当我在Anaconda / Windows上运行它时，我得到了这个回溯：

Traceback (most recent call last):

End of HDF5 error back trace

Unable to open/create file 'chop_x:0:49.hdf5'

我尝试在Anaconda / Win ipython3中手动写入一个完全相同名称的文件，这也很好。我也尝试将名称更改为一个简单的字符串，它起作用，表明我用str.format（）构造的文件名值确实有问题。另一方面，当我做df.to_hdf('chop_x:0:49.hdf5', 'w', 'chop')它工作正常。我怎样才能看到我传递的参数有什么问题？你认为这是另一个参数的问题吗？

不同的操作系统对路径和文件名中允许的字符有不同的限制。

尝试在Windows资源管理器中使用:创建文件名，您就会明白为什么它不起作用。

Naming Files, Paths, and Namespaces

弃权使用：

< (less than)
> (greater than) 
: (colon)
" (double quote)
/ (forward slash)
\ (backslash)
| (vertical bar or pipe)
? (question mark)
* (asterisk)

整数值为零，有时也称为ASCII NUL字符。整数表示形式在1到31范围内的字符，但允许使用这些字符的备用数据流除外。
