Package Contents

class onc.ONC(token, production: bool = True, showInfo: bool = False, outPath: str | pathlib.Path = 'output', timeout: int = 60)[source]

A wrapper class for Oceans 3.0 API requests.

All the client library’s functionality is provided as methods of this class.

Parameters:

token (str) – The ONC API token, which could be retrieved at https://data.oceannetworks.ca/Profile once logged in.
production (boolean, default True) –
Whether the ONC Production server URL is used for service requests.
- True: Use the production server.
- False: Use the internal ONC test server (reserved for ONC staff IP addresses).
showInfo (boolean, default False) –
Whether verbose script messages are displayed, such as request url and processing time information.
- True: Print all information and debug messages (intended for debugging).
- False: Only print information messages.
outPath (str | Path, default "output") – The directory that files are saved to (relative to the current directory) when downloading files. The directory will be created if it does not exist during the download.
timeout (int, default 60) – Number of seconds before a request to the API is canceled due to a timeout.

Examples

>>> from onc import ONC
>>> onc = ONC("YOUR_TOKEN_HERE")  
>>> onc = ONC("YOUR_TOKEN_HERE", showInfo=True, outPath="onc-files")  

print(obj, filename: str = '') → None[source]

filename (str, default "") –
The filename that is used when saving the json file. It is relative to self._out_path. The .json extension could be omitted.
- if not empty, save the output to the file.
- if empty, print the output to the console.

Examples

>>> result = onc.getLocations()  
>>> onc.print(result)  

formatUtc(dateString: str = 'now') → str[source]
