python调用fortran模块

1.在$PATH中添加gfortran的路径，我的是c:\Program Files\pythonxy\mingw\bin\

2.在$PATH中添加python的路径，我的是c:\Python26\

3.新建环境变量C_INCLUDE_PATH，添加gfortran头文件的路径，我的是c:\Program Files\pythonxy\mingw\include\

好啦现在f2py就可以用了。新建fortran程序foo.f90如下

foo.f90

subroutine hello (a)
 
integer a
 
  write(*,*)'Hello from Fortran90!!!',a
 
end subroutine hello

编译

f2py -m foo -c foo.f90 

运行

$ python
Python 2.7.6 (default, Jun 22 2015, 17:58:13) 
[GCC 4.8.2] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import foo
>>> foo.hello(15)
 Hello from Fortran90!!!     15

另外附上f2py支持的数据类型有

integer[ | *1 | *2 | *4 | *8 ], logical[ | *1 | *2 | *4 | *8 ]
integer*([ -1 | -2 | -4 | -8 ])
character[ | *(*) | *1 | *2 | *3 | ... ]
real[ | *4 | *8 | *16 ], double precision
complex[ | *8 | *16 | *32 ]
 | : | * | :
intent([ in | inout | out | hide | in,out | inout,out | c |
     copy | cache | callback | inplace | aux ])
dimension()
common, parameter
allocatable
optional, required, external
depend([])
check([])
note()
usercode, callstatement, callprotoargument, threadsafe, fortranname
pymethoddef
entry
