why is that ? not sure it is best practice, but I tend to use try except block to avoid inference errors.

Sorry for the confusion, the try-except warning is only for import statements, not regular code.

Especially for such situation:

try:
    import pandas
except ImportError:
    %pip install pandas
    import pandas

There is more details in the documentation:

Importing at a level other than the very top level will not work.
Wrapping it in a try-except or if-else statement will generate a warning. The import will be ignored.
Imports in functions are also ignored but do not generate warnings.
