How to pass a python variables to shell script in azure databricks notebookbles.?
Per my experience, there are two workaround ways to pass a Python variable to Bash script for your current scenario.
Here is my sample codes using Python3 in notebook.
To pass little data via environment variable in the same shell session of Azure Databricks Notebook, as below.
%pythonimport osl = ['A', 'B', 'C', 'D']os.environ['LIST'] = ' '.join(l)print(os.getenv('LIST'))%%bashfor i in $LISTdo echo $idone
It works as the figure below.
To pass large data via file in the current path of Azure Databricks Notebook, as below.
%pythonwith open('varL.txt', 'w') as f: for elem in l: f.write(elem+'\n') f.close() %%bashpwdls -lh varL.txtecho '=======show content=========='cat varL.txtecho '=====result of script========'for i in $(cat varL.txt)do echo $idone
It works as the figure below.
