What is the benefit of "+" sign when I can add two strings without it?

Question

Example:
print("You" ", " "Me")
is similar to
print("You"+", "+"Me")

Answer 1

Because of this:

>>> a='v'
>>> print('aa' a)
SyntaxError: invalid syntax
>>> print('aa'+a)
aav

If your text is in a variable, you need the '+'

Answer 2

But I don't even mention any variable in my question #Cosme

Answer 3

comma uses a space by default. Change it with the sep = 'choose any char'. Convenience. I think formatting is used more than either of these ways.
