This line :
myvar = b'hi'
causes an IDE error against it. The hover message reads :
"Syntax Error - invalid string (possibly contains a unicode character)"
It doesn’t affect execution of the code, however.
Nice catch! This is a bug in the Python parser we use for our autocompleter. I’ve registered this in our bug-tracking database, and we’ll work on getting that fixed.
