Write a python script to simply display hello world!
Here's a simple Python script to display hello world! on the console:

```python
print(hello world!)
```

Save this code in a file with a `.py` extension, such as `hello.py`. Then, run the script by opening a terminal or command prompt, navigating to the directory where the script is saved, and typing `python hello.py`. The output should be:

```
hello world!
```
Can you write a C++ program to do the same thing?
Sure! Here's a C++ program that displays hello world! on the console:

```c++
#include <iostream>

int main() {
    std::cout << hello world! << std::endl;
    return 0;
}
```

Save this code in a file with a `.cpp` extension, such as `hello.cpp`. Then, compile and run the program by opening a terminal or command prompt, navigating to the directory where the program is saved, and typing:

```
g++ hello.cpp -o hello
./hello
```

The output should be:

```
hello world!
```
