本地意味着它们将在给定的目录中可用。这是通过在这个目录中放置一个文件python-version.txt来完成的。这对版本控制的存储库很重要,但是有一些不同的策略来管理它们。一种是将该文件添加到“忽略”列表中。这对开源项目的异质团队很有用。另一种方法是签入这个文件,以便在这个存储库中使用相同版本的 Python。 注意...

if in above scenario, the correct way is to first store the modification somewhere else. Iterate the list entirely one time. Can use list.copy() or list[:] as the orignial list. Another example is looping through dictionary keys:
If at any moment, there is a stable Python release that is not in this list, rest assured it is being worked on and will be added. Important For Python 3.4 and only that version, we need other Python version as a compile time dependency. Nuitka itself is fully compatible with all ...
