Passing Parameters from SAS to Python Script

Balli — Tue, 09 May 2023 05:44:36 GMT

Hello Team,

I am writing this python script to upload the files to SFTP and I want to dynamically pass the file name as a macro variable. Unfortunately we can not use the submit block inside a macro function. Can someone please help me with a solution ? or an alternative way to SFTP the files?

Hi @Balli

You can't call macro variables in the script that way, instead the macro variable needs to be passed using the SAS variable which is created as part of the PROC PYTHON session.

You should be able to use SAS.symget('') where you've highlighted the issue in your code in yellow.

see example from documentation below:

%let myvar = Jane Doe;

proc python;
submit;
x = SAS.symget('myvar')
print('macro variable myvar = ' + x)

py_var = 'Inside python'
SAS.symput('macrovar', py_var)
endsubmit;
run;

%put &=macrovar;
%put &=myvar;

Thanks

Harry
