Just to protect against creation of misinformation:


print foo , bar  ->  print ( foo , bar )

Also the "%s" and % operator are deprecated in Python 3, so:

print ( "%s %s" % ( foo , bar ) ) -> print ( "{} {}".format ( foo ,
bar ) )

Why?

except Foo , e : ->  except Foo as e :


I find that the following document is very helpful:
