Is there a way to use bash subshells to enter internal input to a program?

Question

I know you can use subshells to feed a program arguments, like:

./myProgram $(python2 -c "print 'SomethingHere'")

But let's assume that after running the program, it asks for more inputs. For example:

./myProgram SomethingHere
[+] Argument Processed!
[+] Please Enter an Access Code: 

Is there a way the I can pass the access code via a subshell?
