Stmdency, **ST**ate**M**ent depen**DENCY** is a Python library for extracting dependencies between Python statements.

## Installation

```shell

python -m pip install --upgrade stmdency

```

## Usage

Let's say we have a Python script named  `test.py` with the following content:

```python

a = 1

b = 2

def bar():

   b = a + 3

   print(a, b)

def foo():

   bar(b)

```

We want to extract function `foo` and all its dependencies. `stmdency` can do this for us:

```python

from stmdency.extractor import Extractor

with open("test.py", "r") as f:

   source = f.read()

   extractor = Extractor(source)

   print(extractor.get_code("foo"))

```

The output will be:

```python

a = 1

def bar():

    b = a + 3

    print(a, b)

b = 2

def foo():

    bar(b)

```
