# Convert to Enumerate

#### Sourcery refactoring id: `convert-to-enumerate`

#### Description:

Replaces manual loop counter with call to `enumerate`

#### Before:

```python
i = 0
for currency in currencies:
    print(i, currency)
    i += 1
```

#### After:

```python
for i, currency in enumerate(currencies):
    print(i, currency)
```

#### Explanation:

When iterating over a list you sometimes need access to a loop counter that will
let you know the index of the element you are utilising.

Using the built-in Python function, `enumerate`, lets you generate an index
directly, removing two unneeded lines of code.

When reading this we don't have to worry about the book-keeping of the `i`
variable, letting us focus in on the code that really matters.
