# pylinqext
pylinqext is a package for C#er to write code like LINQ.

## Usage
```python
from pylinqext import pylist
from pylinqext import enumerable
  
e = enumerable([1,2,3,4,5,6,7,8,9,0])
  
e.where(lambda x: x % 2 == 0)\
        .select(lambda x: x * x)\
        .where(lambda x: 30 < x)\
        .to_pylist()\
        .for_each(lambda x: print(x))
```
Output:
```
36
64
```
```python
from pylinqext import enumerable, pydict

d = pydict({1:1, 2:4, 3:9})
d.items()\
    .where(lambda x: x[0] >= 2)\
    .to_pydict(lambda x:x[0], lambda x:x[1])\
    .for_each(lambda k,v: print(f"key={k},value={v}"))
```
Output:
```
key=2,value=4
key=3,value=9
```
