python - How to use extra arguments passed with Variable file - Robot framework -

in robot framework user guide there section describes how pass variable files , possible variables if needed.
example:
pybot --variablefile taking_arguments.py:arg1:arg2

my question can use these possible variables arg1 , arg2 in taking_arguments.py file afterwards , if can how?

right have this:

pybot --variablefile taking_arguments.py:arg1:arg2

taking_arguments.py contents:

ip_prefix = arg1

but results in

nameerror: name 'arg1' not defined

the way use variables in argument file using --variablefile filename.py:arg1:arg2 syntax have variable file implement function get_variables. function passed arguments specify on command line, , must return dictionary of variable names , values.

for example, consider following variable file, named "variables.py":

def get_variables(arg1, arg2):     variables = {"argument 1": arg1,                  "argument 2": arg2,                 }     return variables 

this file creates 2 robot variables, named ${argument 1} , ${argument 2}. values these variables values of arguments passed in. might use variable file this:

pybot --variablefile variables.py:one:two ... 

in case, strings "one" , "two" passed get_variables 2 arguments. these associated 2 variables, resulting in ${argument 1} being set one , ${argument 2} being set two.
