filename extension

基本解釋

In many cases, you can switch from one data type to another just by changing the filename extension.
在許多情況下，您可以從一種數(shù)據(jù)類型切換到另一種數(shù)據(jù)類型，只需更改文件擴展名即可。
Simply switch the filename extension, and, if the particular method supports it, you get a newly formatted data stream.
切換文件擴展名就行，而且，如果有特定的方法支持它，那么就獲得了新格式化的數(shù)據(jù)流。
Finally, --doctest-extension lets you specify a filename extension of your own choice (most developers I know would choose .txt or .rst or perhaps .doctest).
最后，--doctest-extension 允許指定文件擴展名（我認識的大多數(shù)開發(fā)人員選擇 .txt、.rst 或 .doctest）。
