[ANALYSIS] Fix syntax in python scripts

[iarspider]

PR description:

Fix syntax in python scripts:

• Switch to python 3 syntax: print(), except ... as
• Partial fix for indentation: make all indented line use the same characters for indentation (either spaces or tabs), remove mixing of tabs and spaces
• Add missing braces and commas, fix invalid syntax (FWLiteEnabler::enable() should be ROOT.FWLiteEnabler.enable()), remove trailing semicolons
• Replaced (potentially unsafe) exec with import_module

This is a preparation for fixing #46113 . Maybe some of these scripts are not needed anymore and can be removed?
