#Python Intermediate

Exercises proposed in the Python Candies lesson about intermediate-level Python development and quick interaction prototyping.

The descriptions of each exercise are reported below:

###Exercise 3 - Text To Speech

Write a program to make the computer «speak» text strings given by users on the console. The program must ask for new words until the word «exit» is entered, in such a case it should greet the user by saying «Goodbye».

Suggestion:

• check how the Google’s tts service works

###Exercise 1 - System metrics

Write a program to provide a set of system metrics :

• the current load average,
• the operating system version, name, architecture,
• the total and the free memory
• Add some information on CPU and disk usage

Monitor the CPU percentage value and trigger a vocal warning if the CPU goes over a given threshold, e.g., 10%.

Suggestion:

• The psutil module offers system-independent access to the O.S. performance metrics

###Exercise 2 - Music crawler

Write a program that, given a starting folder, crawls all the folder sub-directories to find music files.

• Root folders are provided at the program prompt, on the command line
• Typing the word «exit» stops the program execution

Suggestion:

• The os module allows to access operating system facilities (e.g., bash commands)
• Consider .mp3 and .flac files only

###Exercise 4 - Mp3 Player

Write a program for playing a given mp3 audio file.

Suggestion:

• Exploit the mplayer software as in the Text To Speech exercise

###Exercise 5 - Vocal mail fetch

Write a program that:

• Monitors your inbox folder for unseen messages
• Provides a vocal summary of newly received messages including the message count, and for each message the sender(s) and the title

Suggestion:

• Assume that the mail server is accessible through IMAP
• The Python modules that enable mailbox access and mail reading are: imaplib and email
