-2

I have argument in my script called attach_sub which take 2 argument

 attach_sub (host_id, vdc_sub_id)

I need to provide attach_sub function a second argument which is the value of

prm_vdc_id variable

let say 

prm_vdc_id = 5

I got a variable called vdc_sub_id which should be yielding the value of prm_vdc_id

vdc_sub = 'prm'
vdc_sub_id = vdc_sub+'_vdc_id'
'prm_vdc_id'

but I am getting vdc_sub_id value as a string and not the actual

value of prm_vdc_id to be assign to the function

in short I want the function to take vdc_sub_id as its second argument

with a value of 5 in this case

attach_sub (host_id, vdc_sub_id)

any help will be appreciated

Use exec(vdc_sub_+"_vcd_id"), but you probably shouldn't code this way.

You're probably doing something wrong here, but the reason why you're getting a string is because you're adding the two strings. If you want the variable which corresponds to the string value, do:

eval(vdc_sub_+"_vcd_id")

A better way of going about this would be to us a dictionary of sub_ids, where any possible value of vdc_sub corresponds to a xxx_vdc_id:

sub_ids = {'prm': 5}

Now, the equivalent of xxx_vdc_id would be sub_ids[xxx].
