Issue with Variable Scope in Python within Generator Expressions

[melv33n]

I am facing an issue in Python where variables within generator expressions (such as all(...) or list comprehensions) are not accessible unless declared globally. For instance, in all(row[column] == fieldData for row in eventsList), both column and eventsList are not accessible in that context, resulting in the exception: name 'eventsList' is not defined. Does anyone know how to solve this without declaring the variables globally?

This won't work:

column = 'some_column'
fieldData = 'expected_value'
eventsList = [{'some_column': 'expected_value'}, {'some_column': 'other_value'}]

if all(row[column] == fieldData for row in eventsList):
    print("All rows match")
else:
    print("Not all rows match")

but will do if I append global column, fieldData, eventsList at the beggining

Hey!

Is this in the Execute Python function, Liquid or with a custom app?

It indeed must have something to do with local vs global scopes if the execute python function 🤔

It's in Execute Python Function inside Shuffle-tools app

@0x0elliot can you look into this? Very relevant to the code editor work
