# Str Prefix Suffix

#### Sourcery refactoring id: `str-prefix-suffix`

#### Description

Replace explicit str prefix/suffix check with call to `startswith`/`endswith`.

#### Before

```python
name[:8] == "Sourcery"
name[-8:] == "Sourcery"
```

#### After

```python
name.startswith("Sourcery")
name.endswith("Sourcery")
```

#### Explanation

When we read code like `name[:8] == 'Sourcery'` it takes a moment to understand
exactly what it is doing. Instead when we read `name.startswith('Sourcery')` or
`name.endswith('Sourcery')` it is immediate clear what the intent of the code
is. Additionally we don't have to manually count the length of the prefix and
check it is the same as the slice end; if we ever change the prefix we are less
likely to make a mistake.
