The file L4P5.zip contains words.txt, a list of words, and histogramfun.py, a template for a histogram function. In this problem, you will be writing code to plot a histogram of the proportion of vowels in each word of a given wordList. Vowels are 'A', 'E', 'I', 'O', 'U'.Make sure to put a title and appropriate labels on the plot.When you have produced a plot, answer the following question, to check your solution and your understanding of it.Using the code you wrote to investigate, do more words in the word list have a vowel proportion greater than or less than 0.5?
