# Identity Comprehensions

#### Sourcery refactoring id: `identity-comprehension`

#### Description

Convert list/set/tuple comprehensions that do not change the input elements into

#### Before

```python
# List comprehensions
[item for item in coll]
[item for item in friends.names()]

# Dict comprehensions
{k: v for k, v in coll}
{k: v for k, v in coll.items()}  # Only if we know coll is a `dict`

# Unneeded call to `.items()`
dict(coll.items())  # Only if we know coll is a `dict`

# Set comprehensions
{item for item in coll}
```

#### After

```python
# List comprehensions
list(iter(coll))
list(iter(friends.names()))

# Dict comprehensions
dict(coll)
dict(coll)

# Unneeded call to `.items()`
dict(coll)

# Set comprehensions
set(coll)
```

#### Explanation

All these comprehensions are just creating a copy of the original collection.
They can all be simplified by simply constructing a new collection directly. The
resulting code is easier to read and shows the intent more clearly.
