Try it:
Below you’ll see some example python code that contains a shopping list
Press Ctrl + Enter
to run the code.
This code creates a list called farm
and adds three strings to that list: "cat"
, "dog"
and "mouse"
Line 4 iterates through each string in the list using the variable animal
to keep track of which animal the current iteration is working with. For example, animal
stores "cat"
the first time line 5 runs but then animal stores "dog"
on the next iteration of line 5 and "mouse"
on the final iteration of line 5.
Challenges:
Start by running the code.
- Change the cat to a pig
When the code first runs you should see:
Old McDonald had a farm E-I-E-I-O And on that farm he had a cat E-I-E-I-O Old McDonald had a farm E-I-E-I-O And on that farm he had a dog E-I-E-I-O Old McDonald had a farm E-I-E-I-O And on that farm he had a mouse E-I-E-I-O
Change line 2 so that you see this when the code runs instead:
Old McDonald had a farm E-I-E-I-O And on that farm he had a pig E-I-E-I-O Old McDonald had a farm E-I-E-I-O And on that farm he had a dog E-I-E-I-O Old McDonald had a farm E-I-E-I-O And on that farm he had a mouse E-I-E-I-O
- Add a zebra to the farm
Add a new string inside the list on line 2
- Repeat the whole song 5 times
It might be helpful to look back at the theory page for this. You’ll need to choose which lines of code you want to repeat 5 times then indent them all (select and press
tab
) then writefor i in range(5):
above them.
On the next page you’ll get some code with both syntax and logic errors
