Convert a text to a dictionary of words

Write a function called text_to_dic that receives a text as an argument. It must create and return a dictionary where the keys are the words in the text, and their values are the number of occurrences of each of these in the text.

Use the function you just wrote to define a function called file_to_dic that receives the name of a text file and returns a dictionary where the keys are the words of the text in the file and its values the number of appearances of each of these in the text of the file.

Don’t forget your documentation and pytests. To facilitate the creation of your test cases, in Poliformat there is a text.txt file that contains the following dictionary:

'Es': 13, 'un': 52, 'hecho': 13, 'hace': 11, 'tiempo': 8, 'que': 23, 'lector': 9, 'mira': 13, 'el': 11, 'de': 26, 'texto': 13, 'sitio': 11, 'mientras': 9, 'que.': 3, 'contenido': 10, 'mira.': 10

A histogram is a graphical representation of a variable in the form of bars, where the area of each bar is proportional to the frequency of the values represented. They are used to obtain a general “first view” or panorama of the distribution of the population, or of the sample, regarding a characteristic, quantitative and continuous (such as length or weight) (see https://es.wikipedia.org/wiki/Histograma).

Write a function ascii_histogram that receives as an argument a dictionary with keys of type string and values of type int, and returns an ASCII histogram that uses the Python output format. An example is below:

>>> ascii_histogram(file_to_dic("text.txt"))
                Es +++++++++++++
                un ++++++++++++++++++++++++++++++++++++++++++++++++++++
            hecho +++++++++++++
            hace +++++++++++
            tiempo ++++++++
            que +++++++++++++++++++++++
            lector +++++++++
            mira +++++++++++++
                el +++++++++++
                de ++++++++++++++++++++++++++
            texto +++++++++++++
            sitio +++++++++++
        mientras +++++++++
            que. +++
        contenido ++++++++++
            mira. ++++++++++

Create a test case to test the function ascii_histogram that returns as expected result:

>>> ascii_histogram(dic)
                0 
                1 +
                2 ++
                3 +++
                4 ++++
                5 +++++
                6 ++++++
                7 +++++
                8 ++++
                9 +++
                10 ++
                11 +
