[Solved] SOLVED:Analyze a text file to produce

# Analyze a text file to produce# a list of words (in alphabetical order) with their frequencies# a list of letters (also in alphabetical order) with their frequencies## Words will all be converted to lower case and have any puncutation# marks removed.# ***** function takes a word as input and returns# ***** as lower case with all punctuation removed.## *****: convert the word to lower case.# ***** through the word one character at a time, and if it is# ***** a-z, add it to a new word.def lower_letters_only(word):lower_word = word = word.lower()for letter in word:if letter in abcdefghijklmnopqrstuvwxyz:lower_word+= letterreturn lower_word# This function will repeatedly ask for a file name# and return a file object when it is able to successfully# open the file. Hint: use try/except and use a boolean variable# such as valid_file to indicate whether you had a valid file or not.def get_input_file(fn): #fn file namewhile True:print(enter + file_type + filename: )filename = input()print(filename)try:with open(filename, r) as f:my_file = f.read()return my_fileexcept FileNotFoundError:print(No such file. Check file name and path and try again.)except IOError:print(File does not exist)pass## This function will take as its input a dictionary# and will print the contents with the keys in alphabetical# order.
