Function Extraction
===

## High level idea

1. Take source code
2. Run file namned "function_level.py"
3. Extract functions/classes
4. Save each extracted function/class separately as a .py file

:::success
function_level.py takes an argument (the path of the current directory i.e., where all the files are stored)
:::

Code
---
You can run the code as follows

Save all the files you want to run this script on in the current working directory
run: python3 currentWorkingDirectory

Naming Convention
---
The naming convention of the saved files is as follows:
1. If a source code (called test.py) is:

class abc:
    self.lock = _thread.lock()

class xyz:
    self.lock = _thread.allocate_lock()

def pqr(new, old):
    x = "hello" + old + new

def stu(name):
    return type(sys)(name)

The code above will be split into **4** files, namely:
1. test_class_1.py (for class abc)
2. test_class_2.py (for class xyz)
3. test_function_1.py (for function pqr)
4. test_function_2.py (for function stu)

Extra info/limitations
---
1. If you want to remove comments from the source code, uncomment line 73
2. This script does not handle nested functions/classes. A class of this structure is saved as **1** file:

class xyz:

    def __init__(self, name):
        self.lock = _thread.allocate_lock()

    class abc:
        def __exit__(self, name):
        self.lock = _thread.lock()
