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，其中代码运行在系统 Python3 和 Anaconda Python 上都很好3 名口译员。但是，当我在 Anaconda/Windows 上运行时，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 中手动写入完全相同名称的文件，这也工作正常。我还尝试将名称更改为一个简单的字符串，这很有效，这表明我传递的文件名值确实有问题，这是用 str.format() 构造的。另一方面，当我执行 df.to_hdf('chop_x:0:49.hdf5', 'w', 'chop') 时，它工作正常。我怎样才能看到我传递的参数有什么问题？你觉得是不是另一个参数的问题？

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 资源管理器中创建一个带有 : 的文件名，您就会明白为什么它不起作用。

Naming Files, Paths, and Namespaces

放弃使用：

< (less than)
> (greater than) 
: (colon)
" (double quote)
/ (forward slash)
\ (backslash)
| (vertical bar or pipe)
? (question mark)
* (asterisk)
Integer value zero, sometimes referred to as the ASCII NUL character. Characters whose integer representations are in the range from 1 through 31, except for alternate data streams where these characters are allowed.

（摘自上面link的东西，里面还有很多，看吧。）
