Common errors

error ModuleNotFoundError: No module named 'hello-world' ↓

cause Using hyphen in import instead of underscore.

fix

Use 'import hello_world' (underscore).

error AttributeError: module 'hello_world' has no attribute 'hello_world' ↓

cause Assuming the function is named hello_world.

fix

Use hello_world.hello().

gotcha Package name uses hyphen 'hello-world' but import uses underscore 'hello_world'. This is a common Python convention. ↓

fix Use 'import hello_world'.

gotcha The main function is called 'hello()', not 'hello_world()'. Check the source if in doubt. ↓

fix Call hello_world.hello().

hello_world
wrong
```
import hello-world
```
correct
```
import hello_world
```
Hyphen in package name becomes underscore in import.

Imports and calls the hello function.

import hello_world

hello_world.hello()
