Description: # Py ToolBelt
        This module contains basic functions for built-in datatypes for execute trivial tasks.
        This functions are available as built-in datatype methods.
        
        ## Installation
        Install package using pip -> `pip install py-toolbelt`
        
        ## Usage
        Import the module and activate toolbelt
        `
        import py_toolbelt
        py_toolbelt.activate()
        `
        After activation, custom functions are available as built-in methods.
        For example -
        Before activation, in python console, create a list variable `list_object = [1, 2, 3]` and type `list_object.` and press tab to get prompt of available methods, you see -
        ```python
        >>> list_object.
        l.append(   l.clear(    l.copy(     l.count(    l.extend(   l.index(    l.insert(   l.pop(      l.remove(   l.reverse(  l.sort(
        ```
        
        After activation -
        ```python
        >>> list_object.
        l.append(         l.count(          l.filter(         l.insert(         l.pop(            l.reverse(        l.to_tuple(
        l.clear(          l.count_all(      l.flat_list(      l.intersection(   l.remove(         l.sort(           l.transform(
        l.compact(        l.execute(        l.get_index(      l.is_none(        l.remove_index(   l.to_dict(        l.unique(
        l.copy(           l.extend(         l.index(          l.is_not_none(    l.remove_values(  l.to_set(

        ```
        
        ### multithread_pool(`funcs`, `max_threads=5`)
        This method execute given ``funcs`` dict of functions in multi-thread. Each thread execute one function.
        
        **Arguments**
        * __funcs__ - dict
        * __max_threads__ - int, (_optional_, _default: `5`_)
        
        **Example**
        `funcs` argument dict keys are function and value is either list of length 2 or ``None``.
        List 1st element should be list of positional arguments.
        List 2nd element should be dict of keyword arguments.
        If key is ``None`` then it means function do not take any positional arguments and keyword
        arguments.
        Structure -
        ```python
        {test_func1: [[1, 2, 'Hello', [1,2,333]], {'arg_key': 12}],
         test_func2: [[1, 2, 'Hello', [1,2,333]],

         test_func: None}
         ```
        
         ### cache_db(`key`, `value=None`)
        This function use to implement temporary small pickle database which is a json storing file.
        This is not persistant database so it will be cleared out if you deploy new code / delete the pickle file.
        So make sure to use in such cases where you need data to store for temporary purpose.
        This function accept two parameters, first is `key` and second is `value`.
        If only `key` parameter is provided then it will get data from database, if `key` not found return ``False``, otherwise return key's value.
        If you pass both `key` and `value` parameters then it will set key value in database.
        
        **Arguments**
        * __key__ - str
        * __value__ - any basic datatype accepted by json format, (_optional_, _default: `None`_)
        
        **Example**
        ```python
        >>> cache_db(key='hello')
        False
        >>> cache_db(key='hello', value='world')
        True
        >>> cache_db(key='hello')
        World
        ```
        ### none_safe(`object`, `default=None`)
        If given `object` is not `None` then return object otherwise return `default` value.

        * __object__ - any data type / object
        * __default__ - any data type / object, (_optional_, _default: `None`_)
        
        **Example**
        ```python
        >>> none_safe(5)
        5
        >>> none_safe('hello', 'world')
        hello
        >>> none_safe(None, 'world')
        world
        ```
        
        ### iter_safe(`object`, `default=[]`)
        If given `object` is not `None` and object is instance of iterable then return object otherwise return `default` value.
        
        **Arguments**
        * __object__ - any data type / object
        * __default__ - any data type / object, (_optional_, _default: `[]`_)
        
        **Example**
        ```python
        >>> iter_safe(5)
        []

        ['hello']
        >>> iter_safe([], 'world')
        []
        >>> iter_safe('hello')
        'hello'
        >>> iter_safe(1.4, ['hello', 'world'])
        ['hello', 'world']
        ```
        
        ### empty_safe(`object`, `default=None`)
        If given `object` is empty in sense of iterable then return `default` value else return `object`.
        
        **Arguments**
        * __object__ - any data type / object
        * __default__ - any data type / object, (_optional_, _default: `None`_)
        
        **Example**
        ```python
        >>> empty_safe(5)
        5

        ['hello']
        >>> empty_safe([], 'world')
        'world'
        >>> empty_safe('hello')
        'hello'
        >>> empty_safe(1.4, ['hello', 'world'])
        1.4
