# Exercise 1
## About `common.py`
I've copied the function inputTypeCheck() into a common.py for each directory. Normally, I would've made it a module, but to avoid system specific bugs, I've decided not edit global environment variables like PYTHONPATH or edit the sys.path. This means, at least as far as I know, that I can't use relative imports.

# TDT4109 ITGK Øvinger
Dette er en [git-repo][git-repo] hvor jeg samler opp alle øvingene for TDT4109.
## Kjøring
Flere av skriptene deler funksjoner fra mappen `common`. For at disse skal kjøre på en korrekt måte, må de kjøres som moduler og ikke alenestående skript.
Eksempel på hvordan man skal kjøre en fil:
```bash
python3 -m "Exercise 3.11 - Doble lokker.11a"
```
Eksempel på hvordan man **ikke** skal kjøre filen:
```bash
python3 "Exercise 3/11 - Doble lokker/11a.py"
```
## Testing
Hver oppgave kommer med eksempel på kjøring, og dette eksempelet i tillegg til andre eksempler blir testet med python sitt innebygde bibliotek som heter `unittest`. Hver øving har en mappe som heter test, hvor alle testene for de forskjellige skriptene ligger, og man kan automatisk teste en av- eller alle filene med kommandoen:
```bash
python -m unittest -s 'Exercise <x>/test'
```
## Komprimering og innlevering
I hovedmappa ligger det en fil med navn `zipExercise.py`. Denne tar inn ett mappenavn som argument, og sørger for å inkludere alle `common`-modulene som ble brukt, fjerne `__pycache__`, i tillegg til å kopiere denne readme-filen inn i zip-mappa.
Eksempel på bruk:
```bash
python zipExercise.py "./Exercise 3"
```
