What to do

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

jupyter-example
     jupyter-example.ipynb
     jupyter-example-sol.ipynb
     jupman.py
     my_lib.py

WARNING: to correctly visualize the notebook, it MUST be in an unzipped folder !

• open Jupyter Notebook from that folder. Two things should open, first a console and then browser. The browser should show a file list: navigate the list and open the notebook jupyter-example/jupyter-example.ipynb

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

Shortcut keys:

• to execute Python code inside a Jupyter cell, press Control + Enter

• to execute Python code inside a Jupyter cell AND select next cell, press Shift + Enter

• to execute Python code inside a Jupyter cell AND a create a new cell aftwerwards, press Alt + Enter

• If the notebooks look stuck, try to select Kernel -> Restart

# REMEMBER TO  IMPORT jupman !
# This cell needs to be executed only once, you can usually find it at the beginning of the worksheets

import jupman

x = [1,2,3]
y = x
jupman.pytut()

Exercise 2

Implement upper function

Show solution

def helper2(x):
    return x.upper()


def upper(x):

    return helper2(x)

def upper(x):
    raise Exception('TODO IMPLEMENT ME !')

Exercise 3

Note everything after the ‘write here’ comment will be discarded. Note you can put how many spaces you want in the comment

Show solution

w = 5

#  write here

x = 5 + 6
y = 6.4
z = x / y

w = 5

#  write here

Exercise 4

Shows how to completely remove the content of a solution cell (including the solution comment)

EXERCISE: write a function that prints ‘hello’
