Question

我的任务是将Fortran 77代码包装到python3中。我试图用以下命令将其包装

inside

f2py出现以下错误

f2py -c mum1_6.f -m mum

代码的相应部分：

running build
running config_cc
unifing config_cc, config, build_clib, build_ext, build commands --compiler options
running config_fc
unifing config_fc, config, build_clib, build_ext, build commands --fcompiler options

我不明白的是'！'是什么问题。注释？如果删除它们，不会引发错误。也有很多行带有相同的“！”在这部分代码之前的注释。实际上，我要包装的文件非常有趣，而且几乎在每一行上都有这样的注释。我不知道为什么f2py只有一部分问题。

我试图考虑所有这些问题，并得出结论，这些评论实际上不是Fortran 77标准的一部分，并且可能是这种情况。因此，我决定将扩展名更改为“ .f90”，然后再次运行f2py。这个问题似乎已经解决了。正如我在几个站点上所读到的那样，Fortran 77代码是Fortran 90的子集，因此我确定一切都很好。但是一段时间后，我尝试将一些Fortran 77代码（不是使用f2py而是直接使用编译器）编译为Fortran 90代码，但我发现这并不是那么简单。至少F90编译器不接受老式的'c'注释。

所以我有两个问题：

1）是否可以通过“！”解决这些问题？内联注释而不将文件编译为f90？

2）将我的.f文件作为.f90馈送到f2py甚至正确吗？ f2py是否会在同一个文件中分隔不同的“代码标准”，并以正确的方式进行换行？

不幸的是，我正在谈论的代码非常庞大，可以将其附加在代码段中。

Answer 1

因此，我在将程序与f2py作为F77交互时没有任何运气。我尝试将其作为F90文件提供给f2py，它对我来说很好用，因为Fortran 90编译器了解固定格式表示法。

在将Fortran77文件与感叹号注释接口时，f2py引发“断言错误”
