For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Exchange Rate Conversion answer
Conditionals and Loops example from a Well House Consultants training course
More on Conditionals and Loops [link]

This example is described in the following article(s):
   • Python - fresh examples of all the fundamentals - [link]

Source code: bp Module: Y103

""" 1. You have 100 Singapore dollars, and the exchange
rate is 1 dollar = 37 pence.

Produce a table of exchange rates, showing how 0, 10, 20
(and so on) up to 100 Singapore dollars convert to pounds.

2. In Singapore, a teapot costs 75 dollars. Modify the
previous examples to report an extra output on the end of
each line saying either "You can't afford a teapot" or
"You can afford a teapot and will have xxxxx change" """


current = 0

while current <= 100:
        pounds = current * 0.37
        if current < 75:
                afford = "You can't afford it"
                change = ""
        else:
                change = current - 75
                afford = "Granny will get a prezzie - change "+str(change)

        # Following line gets brackets right in Python 2
        # print current, pounds, afford, change

        # Following line is right in Python 3 and a bit messy printing in Python 2
        # print(current, pounds, afford, change)

        # Following line woks well in both
        print("{} {} {} {}".format(current, pounds, afford, change))

        current += 10
