Looks like there is no need to place space separators after numbers:

$ python3.5 -c "print(1and 0)"
0
$ python3.5 -c "print([1for i in range(1)])"
[1]

Not sure is this a bug or a feature, but I would expect that this should be SyntaxError, same as here:

$ python3.5 -c "1 and0"
  File "<string>", line 1
    1 and0
         ^
SyntaxError: invalid syntax

If this is a feature, can anyone give reasoning for it?
