# Python forráskód és projekt kezelés

Tematika, témák:

* Kód szervezés, modularizálás

* Javasolt könyvtár struktúra, kód struktúra

* Saját package fejlesztése, ami meghivatkozható más projektből

* Unit test

* PEP8

Windows környezet

* Python telepítése Choco-val https://chocolatey.org/

```shell

choco list --localonly

choco outdated

choco install python

python --version

```

## Új projekt

Új könyvtár: `hellosamples`

`hello.py`

```python

print("Hello Python")

```

Jelenleg ismert szervezési formák:

```python

def say_hello(name):

    return f"Hello {name}"

```

```python

class Greeting:

    def __init__(self, name):

        self.name = name

    def say_hello():

        return f"Hello {self.name}" 

```

# Modul - fájl

`hello_controller.py` létrehozása

```python

name = input("What is your name?")

say_hello(name)

```

Importkor meghívódik a modul

```python

if __name__ == "__main__":

```

# Csomag - könyvtár

Átmozgatás `src\hellosamples` könyvtárba, `__init__.py` fájl létrehozása

# Teszteset

Python 3.4 óta a `pip` része

Python Package Index: https://pypi.org/

pytest

A `tests` könyvtárban `test_say_hello`:

```python

def test_say_hello():

    assert say_hello("John Doe") == "Hello John Doe"

```

`requirements.txt` létrehozása:

```

pytest

```

```shell

python -m venv venv

python.exe -m pip install --upgrade pip

pip install -r ./requirements.txt

pytest

```

A `setup.py` tartalma

```python

#env/bin python

from distutils.core import setup

setup(name='hellosamples',

      version='1.0',

      packages=['hellosamples'],

      package_dir={'':'src'}

     )

```

```shell

pip install -e .

pytest -v

```

VS Code - laboredény

# Csomag futtatása direktben

```shell

python -m hellosamples.hello

```

`__main__.py`

```python

say_hello("Anonymous")

```

```shell

python -m hellosamples

```

## Külső csomag használata alkalmazásból

Új könyvtár

```python

import requests

response = requests.get('https://api.github.com/users/vicziani')

user = response.json()

print(user["public_repos"])

```

`requirements.txt`

A `setup.py` tartalma

```python

#env/bin python

from distutils.core import setup

setup(name='hellosamples',

      version='1.0',

      packages=['hellosamples'],

      package_dir={'':'src'}

     )

```

```

pip freeze

```

## Csomagolás Docker konténerbe

```dockerfile

FROM python

WORKDIR app

COPY *.py requirements.txt .

RUN pip install -r ./requirements.txt

ENTRYPOINT python repos.py

```

## Jupyter notebook

`pythontutorial` kvt.

```

jupyter

ipykernel

```

```shell

python -m venv venv

venv\Scripts\activate

python.exe -m pip install --upgrade pip

pip install -r ./requirements.txt

```

Közben a Visual Studio Code megkérdezi, hogy akarjuk-e a létrehozott virtual enviromentet használni, válasszuk, hogy igen.

Majd _F1_, és _Notebook: Select Notebook Kernel_.

## Jupyter és Selenium

`seleniumtutorial` kvt.

`HelloWorld.ipynb`

`requirements.txt`

```

jupyter

ipykernel

webdriver-manager

selenium

```

```shell

python -m venv venv

venv\Scripts\activate

python.exe -m pip install --upgrade pip

pip install -r ./requirements.txt

```
