[FIXED] How to debug with cell magic %debug

Issue

I have troubles trying to use %debug cell magic to debug my code: i am running ths cell

processData(newDataPath='Data/X_old.csv', newSourcePath='./Data - Feb-June-2019.xlsx', destPath='Data/X_2018_2019.csv')

which give me a key error: data['quantity'] quantity key error ....

how can i use %debug to see data.columns for exemple. Whatever i try to print in ipbb, i have the error is not defined: newDataPath is not defined, data is not defined etc

If you need more details please feel free to ask

Thanks

Solution

I figure it out: use u command to step back until my variable is defined, or u 1000 to come back at the start and d to execute step by step
