so initially I was hoping this is all what Python is about, but when I
started looking into it it has a huge amount of additional (mainly OO)

So you think f.write('Hello world') is bloated and file_write(f,'Hello
world')
is not? This is the minimum amount of OO you will see when using Python. But
I guess you will use OO in the long run to *avoid* bloated code:

print name1, age1, sex1, name2, age2, sex2

self.price = price

print per
print inv

Either your program is small. Then you can do it alone. Or you will
reach step 4.
