should be
`from x import bar, baz, foo`.
### Prefer Private Methods
In Python, private methods don't exist in the way that they do in C++, Java, etc.
To declare a method private we must tell the compiler to garble the name. To do this
add two underscores to the prefix of the method name:
```python
# This method can be seen by anyone on import.
def hello_world():
print("Hello, world!")
# This method can only be seen by the module/class it is defined
# in.
def __hello_module():
print("Hello, module!")
```
We only want to expose the absolute bare minimum number of functions to the consumers of
our modules.
