What is the meaning of (!)

Answer 1

Ah that is no operator but just a sign that is written to the screen!

print('Hello!')

leads to the output

'Hello!'

So whatever you put into quotes, is called a string - it is just a row of letters.

And you can combine strings with the + operator:

print('Hello ' + 'world!')

leads to the output

Hello world!

Two strings are tied together, that's all it is.

You should try it out for yourself in Playground and get a feeling for how it works.

Answer 2

It means "NOT".

Answer 3

x is a variable, where the sentence "This is a string" is stored. So in this case writing

print(x + '!')

is the same as writing

print('This is a string' + '!')

which is what I talked about above.

First, there was a number in x, but then it got overwritten with the string.
