PYTHON AS A CALCULATOR

Now complete Task 2 on Worksheet 2 to try out some more basic maths in Python.




Open Python Shell and have a go at the calculations in the table below:

MINI PLENARY

In pairs try

the Mini Plenary task on Worksheet 2.

Did the calculator beat Python??

COMBINING MATHS & TEXT

What will the output from this code produce?

>>> print("11 divided by 4 = ", 11//4, "remainder ", 11%4)

>>> print("111 divided by 4 = ", 111/4)

>>> print("11 divided by 4 = ", 11/4)

Now try Task 3 on Worksheet 2.




MORE TEXT AND MATHS ...

We can use text to label numbers for example: coins = 20 Why???

Reason: If we need to demonstrate how many coins we own more than once and the value of the coins change, we only need to change the number at the start of the program once.

As programmers this can saves us lots of time.

Now try Task 4 on Worksheet 2.
