Language exercises

Put each solution in a separate python module named excerciseN.py where N is the number of the excercise.

mkdir language_excercises
cd language_excercises
touch excercise1.py
touch excercise2.py
# ... and so on ...

1. Write a function dict_values_ascending that accecpts a dictionary as an argument and returns a list of dictionary values in ascending order

2. Write a function named add_dict(dict_1, dict_2) that joins the two dictionaries provided as arguments and returns a single dictionary with all the items of dict_1 and dict_2

3. Write a function that counts the lines of a file. The file name is provided as a function argument. It returns the number of lines in the file.

4. write a module esercizio4.py that reads a list of words from the command line and prints them out on standard output each one inside a <p> HTML tag:

   $ python esercizio5.py ciao hey

   ciao

   hey

5. write a python module esercizio5.py that reads the remote HTTP endpoint http://ialpython.apiary.io/laboratories and prints to standard output all the laboratories with network status down

Django Excercises

Instructions

this goes in a django_excercises folder under /vagrant/python-test

mkdir /vagrant/python-test/django_excercises
cd /vagrant/python-test/django_excercises
touch school_client.py
# ... and so on ....

Features

Implement a django server and a python command line client to manage a school's enrolment system.

Components:

• django project named school_pro
• django app named enrolment
• python command line client named school_client.py

The enrolment app exposes a web service for the command line client to enroll students saving their details in a db.

Store student

The school staff uses the command line client to add a student to the database.

$ python school_client.py enroll John Doe
OK

The command line client prints OK if the operation went correctly.

The clerk can add more students:

$ python school_client.py enroll Jane Austen
OK
$ python school_client.py enroll Jane Austen
OK
$ python school_client.py enroll Jane Austen
OK

Search students

The school staff uses the command line client to list all the enrolled students

$ python school_client.py search Jane
OK listing results:
Jane Austen
Jane Austen
Jane Austen

The client first displays an informative line and then prints out all the matching students one per line.

Bonus: search on both first name and last name.

Persist enrollment date and time (optional)

The system saves date and time of enrolment when the staff enrols a student.

The enrolment date and time is displayed in the search results.

$ python school_client.py search Jane
OK listing results:
Jane Austen enrolled on 2014-01-01T12:00:00
Jane Austen enrolled on 2014-01-01T12:00:00
Jane Austen enrolled on 2014-01-01T12:00:00

HINT 1 use DateTimeField for models

HINT 2 datetime is not natively json-encodable, turn it into a string before encoding it
