Description: # smoothassert
        
        This Package contains custom Assertion methods to compare Pandas.Series objects.
        1. AssertSimilarSeries
        2. Assert_Cos_Sim_Series
        
        
        ## Install
        
        Grab the package using `pip` (this could take a few minutes)
        Try using one of the following:
        
             pip install pip install -i https://test.pypi.org/simple/ smoothassert
        
        ## Getting Started
        
        Import the module
        
            import smoothassert.smoothassert
        
        Or
        Import the method what you want to use directly
        ```python
        from smoothassert.smoothassert import AssertSimilarSeries
        ```
        
        ## Features
        
        ### 1. AssertSimilarSeries
        The use of this method is to check that left and right Series are Equal, or similar with the given error rate.
        The main usage of this method is to use it where you don't want or not able to make a code what works with 0% error rate i.e.: Machine learning models. Because the basic assertions in given in the common packages only have the AssertEqual methods what looks for 100% equality. If you have a Machine learning model what you want to have 80% precision then you can call this method to test it and its not going to raise Assertion error unless there is more error in the output stream.
        
        #### Example
        If we have 2 series what is almost equal in this example it have 1/5 so 20% difference.
        ```python
        import pandas as pd
        from smoothassert.smoothassert import AssertSimilarSeries
        
        A = pd.Series(['a','b','c','d','e'])
        B = pd.Series(['b','b','c','d','e'])
        
        AssertSimilarSeries(A,B)
        
        Output:
        AssertionError: Series are diferent in 20.0% while the allowable limit is 0%
        ```
        But if we raise the error limitation:
        ```python
        import pandas as pd
        from smoothassert.smoothassert import AssertSimilarSeries
        
        A = pd.Series(['a','b','c','d','e'])
        B = pd.Series(['b','b','c','d','e'])
        
        AssertSimilarSeries(A,B,percent=0.2)
        
        Output:
        OK, error rate:20.0
        ```
        Probably you going to use a unittest framework to test your code, what is perfectly fine and its going to work with it as well.
        ### 2. Assert_Cos_Sim_Series
        Check that the left and right values are similar to each other witht the given rate(default 1 token similarity needed).
        Its Good to Assert Categorical data, or strings.For example if you have a multi-class prediction and you have a couple of classes what you want as output but if the modell not finds all the classes but finds some , it can pass the test.
        
        #### Example
        if each value from the left series contain at least one categori/token from the right series then the test will pass.
        ```python
        import pandas as pd
        from smoothassert.smoothassert import Assert_Cos_Sim_Series
        
        out = pd.Series(['red','car','ford','red'])
        expected = pd.Series(['red,car,sport','car','ford,blue,1999','car,red'])
        
        Assert_Cos_Sim_Series(out,expected)
        Output:
        OK
        ```
        You can set the similarity limit as well default its 0 so if there is any similarity it will pass.
        You can set this as:
        ```python
        Assert_Cos_Sim_Series(out,expected,min_sim = 0.2)
        ```
        ## Documantation
        1. AssertSimilarSeries
        Check that left and right Series are Equal, or similar with the given error rate. 
        + s1 Series
        + s2 Series
        + percent: float between 0 and 1 default 0
        the allowable limit of the errors between the series given in percentage/100
        + check_series_type : bool, default True
        Whether to check the Series class is identical.
        + check_names : bool, default True
        Whether to check the Series and Index names attribute.
        + check_dtype : bool, default True
                Whether to check the Series dtype is identical.
        2. Assert_Cos_Sim_Series
        + Check that the cosine similarity between the elements of the two Series is bigger than the min_sim
        + s1 Series
        + s2 Series
        + min_sim: float between 0 and 1 default 0(what means if there is at least one token has to be similar in each row)
        + mute: bool default True
        mutes the writen feedbacks
        ## In development
        + Add check methods
        + Add a changeable text pre processor to Assert_Cos_Sim_Series, Lemmatization,stemm,remove stopwords etc.
