If you are using Linux or other UNIX like system (such as a Mac) the 
'HERE Document' feature [1] of the OS might prove useful:

# File: dummy.py
inputs = {}
inputs["first"] = raw_input("")
inputs["second"] = raw_input("")
for key in inputs.keys():
     print inputs[key]

Then from the command line:
alex at x301n4:~$ python dummy.py << HERE
first input
second input
HERE

On my system[2] the result is:
second input
first input
