Often, when building machine learning models on text, one of the input parameters is the frequency of occurrence of a word in the text. Write Python code that finds the frequency of use of each unique word in the string document_text and stores the result in a dictionary called frequency_of_words. There is no need to convert words to their initial (base) form. To remove extra characters, use the string replacement method; to count, use the list count method. Use document_text = 'There are food courts in the cities that accommodate many people and offer dishes for every taste from all over the world. The fragrant smells wafting from the food courts are so delicious that your mouth will water. In recent years, imported food products have become an integral part of our lives.'
