Start your assignment
You can start working on your copy of Exercise 2 by accepting the GitHub Classroom assignment.
You can also take a look at the open course copy of Exercise 2 in the course GitHub repository (does not require logging in). Note that you should not try to make changes to this copy of the exercise, but rather only to the copy available via GitHub Classroom.
Exercise 2 hints¶
Here are a few things that may be helpful in completing Exercise 2.
List methods¶
In Problem 2 you will likely need two lists and to use the .index()
method.
These were covered in this week’s lesson.
Indentation woes¶
We have not really run into this problem in the lessons, but Python codes are sensitive to how much you indent the start of each line. This is perhaps easiest to see with an example.
name = 'Dave'
dogs = 0
print('My name is', name, 'and I own', dogs, 'dogs.')
If you copy and paste this code into the Jupyter Notebook cell and run it, you will see that is gives an IndentationError
.
dogs = 0
^
IndentationError: unexpected indent
We will see examples later of why indentation matters, but for now just be sure you don’t indent lines to different levels. Thus, the fix is simply to remove the spaces on the second line.
name = 'Dave'
dogs = 0
print('My name is', name, 'and I own', dogs, 'dogs.')
Now, running the code results in the expected output.
My name is Dave and I own 0 dogs.
