Instructor: Welcome back.
I want to quickly touch on the subject
of what we call string concatenation.
Yes, programmers love creating really
complex names when concepts may not be as complex.
So what does string concatenation mean?
Well, it simply means adding strings together.
So I can do hello plus Andrei
and I've concatenated this string.
I've added two strings together.
So if I print this, I get hello Andrei.
So if you ever hear people talk
about string concatenation, that's what they mean.
We're concatenating strings.
By the way, what do you think will happen
if I do hello plus five?
If I click run,
hmm, that's not good, is it?
I get TypeError.
Must be string not int.
So it looks like string concatenation
only works with strings.
We'll explore that a little bit more in the next video.
