Python3, connected strings not working

I'm trying to figure out why my code doesn't work when I'm trying to print a collection of strings. In Python 2 I could usually do:

print ('test is') + ('this')

However, in Python 3 it prodcues the following error:

TypeError: unsupported operand type(s) for +: 'NoneType' and 'str'

I have tried replacing '+' with 'and' which works but the string doesn't come out after that. Can someone please explain to me how and why?

If you want to print two string in Python 3 then you need to contain them all in one bracket, print (('test is ')+('this')), so that it's printed all as one string instead of adding print('test is ')(nonetype) to ('this')(string).

In Python 3 print is not a statement unlike Python 2. It is a function. Moreover that function returns a NoneType.

So when you type print ('test is') + ('this') in Python 3.x, you are trying to add NoneType to str and hence the error.

The correct thing ( I expect you want to do this) is to type :

print('test is' + 'this')
