I need help with Currency calculator and view in browser from live rever

Ok, here goes the first point: In Python 3, print is a function (like input, and others), not a statement (like for, while, yield, etc.). So, you have to replace these lines:

print "Hello world"
print "Some other stuff?"

with these others:

print("Hello world")
print("Some other stuff")

I don’t know about doing that (I always run my code from a cmd prompt), but as far as I know, if you want to run your code with Python 3, you may have to replace /usr/bin/python with /usr/bin/python3.
