我最近使用pip install安装了opencv包,并编写了一小段代码来测试它(cvtest.py)。代码在python空闲shell中运行,但是在命令提示符下运行它会出现错误 Error while finding module specification for 'cvtest.py' (ModuleNotFoundError: __path__ attribute not found on 'cvtest' while trying to find 'cvtest.py') 我尝试卸载并重新安装python和包。使用python -m
我尝试用pip包管理器安装Python2.7的tensorflow==1.1.0,但是在运行命令时会出现以下错误:

我正在开发一个检查特定站点的主机名的程序,我希望能够确保在询问主机名(使用raw_input)时,它以TLD (.com,.net,.org)结尾。我不太确定如何在Python中做到这一点。
