I tried a simple code with julia:
x = readline()
print(String(“Hello, $x!”))
and Julia took the variable as “x!”, instead of “x”.
But, it was just fine when I changed the “!” with “.”
Is “!” a special character or else?
I need some explanation. Thank you!

```julia
julia> x = 3; print(String("Hello, $(x)!"))
Hello, 3!
```

Nothing special about the `!` in this context. It is just that `x!` is a valid variable name.

Thank you for the answer. I didn’t know if Julia accept such “!” character as a valid variable, unlike Python.

you can see a lot of functions has `!` in them, such as `push!`, to hint an in-place operation or side-effect (non-pure).

Perfect. But just to complement, it is worth mentioning that a valid function name is also a valid variable name. So what is seen in function names can also be seen in variable names.
