# Python application structure
|
|
|
|
## Directory layout
|
|
|
|
```
|
|
src/
|
|
cli.py OR app.py
|
|
constants.py
|
|
__init__.py
|
|
tests/
|
|
requirements.txt
|
|
setup.py
|
|
```
|
|
|
|
## `requirements.txt`
|
|
|
|
Dependencies used within the venv for the project, e.g:
|
|
|
|
```
|
|
google-auth==1.35.0
|
|
google-auth-httplib2==0.1.0
|
|
google-auth-oauthlib==0.4.6
|
|
google-api-python-client==2.26.1
|
|
gspread==3.7.0
|
|
requests==2.25.1
|
|
oauth2client==4.1.3
|
|
```
|
|
|
|
## `setup.py`
|
|
|
|
The declaration file for the application, equivalent to `package.json`, e.g:
|
|
|
|
```py
|
|
from setuptools import setup, find_packages
|
|
|
|
setup(
|
|
name="eolas-db",
|
|
version="0.1",
|
|
packages=find_packages(where="src"),
|
|
package_dir={"": "src"},
|
|
install_requires=[
|
|
# List your project dependencies here
|
|
],
|
|
entry_points={
|
|
"console_scripts": [
|
|
"eolas-db=cli:main",
|
|
],
|
|
},
|
|
)
|
|
```
|
|
|
|
The `entry_points` key is important. This is the first execution point of the
|
|
application. Typically you would name your entry-point script as `app.py` or
|
|
`cli.py` and then specify its `main` function.
|
|
|
|
E.g. in `cli.py`:
|
|
|
|
```py
|
|
def main():
|
|
print('run the application')
|
|
|
|
if __name__ == "__main__":
|
|
main()
|
|
|
|
```
|
|
|
|
## `__init__.py`
|
|
