For grins I just wrote one that takes '1 2.3 - 3 4 5 + * /' as

100. Took about 7 minutes to code and test.

I'm quite interested in seeing the sourcecode for that.



Me, too. I'm always interested in cool little Python examples.



Not having read the thread,  this script prints the same result:

inp = raw_input("Gimmi an RPN-expression: ").split()
i=0
while len(inp)>1:
while inp[i] not in "+-*/":
i+=1
print "**", i, inp #1 inp[i-2:i+1] = [str(eval(inp[i-2]+inp[i]+inp[i-1]))]
i-=1
print "***", i, inp #2
print inp[0]


If you delete the two numbered print statements it also has 8 lines
of code. (They are inserted to show what's going on!)
Excuse me if this posting suffers from redundancy.
I'm very interested in Bob's solution, too
