Re: [ferret_users] get variable name

Hi Dalton,

Unfortunately, pyferret.getdata only returns numeric arrays at this time.  Returning string arrays is an the enhancement request list.

You can pass string arrays to PyFerret external functions written in Python.  If you could do whatever you are wanting to do in such an external function, then that would be one way. 

Otherwise I think you would have to write the string array to a file with the ferret commands:

    cancel list /head

    list /file=names.txt /clobber /format=(A)

then read the names from file using standard python methods (such as file.readlines).  Not an elegant solution, but it would work.

Hello all,

I am using pyferret and I've been trying to get an array of strings with the variables' names only. The best I've got in ferret is:

yes? use anom.nc 

yes? let names = ..varnames

yes? list names

VARIABLE : ..VARNAMES

FILENAME : anom.nc

SUBSET   :3 points (X)

 1   / 1:"Q_SEN_AN"  

 2   / 2:"TAUX_AN"   

 3   / 3:"TAUY_AN"   

In python I'd like to have an array like:

var = ['Q_SEN_AN', 'TAUX_AN', 'TAUY_AN']

Any Ideas?

Thanks!
