# Object-Oriented Collection Wrappers in Python

```python
from flist import flist, fmap
```

Start with a regular old list:

```python
l = flist([1,2,3,4,5,6,7,8,9,10])
```

We can filter it:

```python
l.filter(lambda x: x % 3 == 0)   == [3, 6, 9]
```

Chain more stuff:

```python
(l
  .filter(lambda x: x % 3 == 0)  #  [3,   6,   9]
  .map(lambda x: x + 200)        #  [203, 206, 209]
  .size())                       == 3
```
