The error is because you are trying to use the plus operation on a
string and an integere which is incompatible. You need to conveert the
integer to a string using str()

But print already converts arguments to strings for you so you
don't need the + sign just use:

print( ‘ Congratulations, you are now ’, age, ‘ years old’)

Or, more generally use a format string as others have suggested.
The format string will work anywhere you need to insert a value
into a string. print() only works for display purposes.
