stmdency, **sta**tement depen**dency** is a Python library for extracting dependencies between statements in a Python program.
## 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)
```
