Most complex example of a notebook with exercises both in Jupyter and Python files, and ‘advanced’ features

What to do

• unzip exercises in a folder, you should get something like this:

jup-and-py-example
   jup-and-py-example.ipynb
   jup-and-py-example_sol.ipynb
   lab.py
   lab_test.py
   lab_sol.py

• open the editor of your choice (for example Visual Studio Code, Spyder or PyCharme), and edit lab.py file

• Go on reading this notebook, and follow instuctions inside.

Let’s begin

You are going to program a simulator of bouncing clowns. To do so, we are going to load this module:

import local

local.gimme(5)

It was a 5 indeed

Exercise in Jupyter

Implement this function:

Show solution

def hello(s):

    return ['hello',s]*1000


hello_db = hello("Guybrush")

hello_db[:10]

['hello',
 'Guybrush',
 'hello',
 'Guybrush',
 'hello',
 'Guybrush',
 'hello',
 'Guybrush',
 'hello',
 'Guybrush']

def hello(s):
    raise Exception('TODO IMPLEMENT ME !')

hello_db = hello("Guybrush")

hello_db[:10]

['hello',
 'Guybrush',
 'hello',
 'Guybrush',
 'hello',
 'Guybrush',
 'hello',
 'Guybrush',
 'hello',
 'Guybrush']

Full expected output is in file expected_output_db.py, if you can’t manage to solve the exercise, as a last resort you can type: from expected_hello_db import * (DO NOT copy-paste file content, it would probably mess Jupyter up)

from expected_hello_db import *
expected_hello_db[:10]

['hello',
 'Guybrush',
 'hello',
 'Guybrush',
 'hello',
 'Guybrush',
 'hello',
 'Guybrush',
 'hello',
 'Guybrush']

Other example:

hello_db2 = hello("Threepwood")

hello_db2[:10]

['hello',
 'Threepwood',
 'hello',
 'Threepwood',
 'hello',
 'Threepwood',
 'hello',
 'Threepwood',
 'hello',
 'Threepwood']

Exercise using previous output

Write some code which says hello 3 times using previous functionand

print(hello('Guybrush')[:6])

['hello', 'Guybrush', 'hello', 'Guybrush', 'hello', 'Guybrush']

Question in Jupyter

QUESTION: Why learn coding?

Show answer

ANSWER: So they pay me more

x + 1

Some other comment

Some nasty formatting

even more formatting

Exercise in Python

Start editing lab.py in text editor

from lab_sol import *

add

Implement add function:

add(3,5)

8

sub

Implement sub function

sub(7,4)
