Canonical challenge report

Motivation

Retrieve the 10 most popular package in the debian release.

I spent ~ 4 hours understanding the assignment, writing the code, unittests and validate coding styled

Step I took to complete the assignement:

• First undertand the Content file
• Plan a script to extract the desired data
• Writing the script:
  • parse the arg to get the architecture from the runtime parameter
  • download the content file
  • unzip the file
  • read line by line the extracted file
  • apply the string manipulation to extract the packages on the line
  • store number of appearance in a dictionary
  • output the 10 first most present packages
