=====

One another trick is to drop spaces around keywords

>>> 99999and 12345or 9999999999if 'a'in'a' else 88888888or 777777
12345

and pray, the tools from those who are wasting their time in
writing code analyzers or syntax colorizers or doc strings
collectors or ... are finally working. Depending of the tools
the interpretation may vary, but definitely all are producing
erroneous results.
