TE-MPE-EP-3 - coding exercies

Coding exercises assigned as part of the TE-MPE-EP-3 technical assessment.

I will unpublish this repository once you ask me to do so.

First exercise

Execution output

[rdm@rdm-mbp ~/Documents/tech/te-mpe-ep-3-coding-exercises] λ python3 duplicate.py
Actual output matches the expected output.
Expected output: ['a', 'c', 'd']
Actual output: ['a', 'c', 'd']
Actual output matches the expected output.
Expected output: [{'a': 'b'}, {'d': 'e'}]
Actual output: [{'a': 'b'}, {'d': 'e'}]

Second exercise

I decided to name the module json_graph_extractor since it can be used as a generic module to extract information from a JSON file into a graph (so there could be more use cases other than listing packages and their dependencies)

Usage

python -m json_graph_extractor [filename]

If python is not found, you might need to use python3, so the command would be:

python3 -m json_graph_extractor [filename]

Example

From the te-mpe-ep-3-coding-exercises/02-json directory you can run:

python3 -m json_graph_extractor tmp/deps.json

Execution output

[rdm@rdm-mbp ~/Documents/tech/te-mpe-ep-3-coding-exercises/02-json] λ python3 -m json_graph_extractor tmp/deps.json
- pkg1
 - pkg2
  - pkg3
 - pkg3
- pkg2
 - pkg3
- pkg3

Test outcome

[rdm@rdm-mbp ~/Documents/tech/te-mpe-ep-3-coding-exercises/02-json] λ python3 -m unittest tests/test_json_graph_extractor.py
