| 1 | You can use the URL query parameters to add environment variables to a jupyter notebook. | ||
| 2 | |||
| 3 | For example, here is a link to a notebook: | ||
| 4 | |||
| 5 | https:~/~/lab.ebrains.eu/user-redirect/lab/tree/shared/example_path/notebook.ipynb | ||
| 6 | |||
| 7 | To add environment variables that are accessible within that notebook (in this case LAB_MY_VARIABLE) use this URL: | ||
| 8 | |||
| 9 | https:~/~/lab.ebrains.eu/user-redirect/lab/tree/shared/example_path/notebook.ipynb**?LAB_MY_VARIABLE=Hello** | ||
| 10 | |||
| 11 | You can add as many variables as you want but the query string needs to be properly formatted. You can find more info about the query string format [[here>>https://en.wikipedia.org/wiki/Query_string]]. | ||
| 12 | |||
| 13 | //Note**:** For the query parameters to be accessible in the notebook they needs to be prefixed with LAB_ e.g. ?LAB_MY_VARIABLE=4 // | ||
| 14 | |||
| 15 | To access a environment variable in the notebook you can use this snipped: | ||
| 16 | |||
| 17 | {{code}} | ||
| 18 | import os | ||
| 19 | os.environ.get('LAB_MY_VARIABLE') | ||
| 20 | {{/code}} | ||
