Chen Hirsh diagnoses a problem:
A friend called to ask for my help with a weird issue. In a Databricks notebook using Python, he declares and assigns a variable in the first cell. Something like that:
my_var = 1He then runs the rest of the notebook, and somewhere along the way, tries to use this variable, and gets this message:
NameError: name 'my_var' is not definedGoing back to cell 1, and checking the value of my_var, he gets the same error.
Read on for the root cause of the issue, as well as a pair of helpful tips from Chen.
