****IN PYTHON! Write a function named file_stats that takes one string parameter (in_file) that is the name of an existing text file. The function file_stats should calculate three statistics about in_file: the number of lines it contains, the number of words and the number of characters, and print the three statistics on separate lines. For example, the following would be the correct input and output:>>> file_stats('created_equal.txt')lines 2words 13characters 72Note: The number of characters may vary slightly between operating systems. Similarly, the number of lines may vary by 1 line, depending on the method used to calculate it. I attached a picture of my code so far and a picture of what the text file reads.

pls code in pythonplagiarism: This Boolean function takes two filenames. If any line occurs in both files, return True.If not, return False. I suggest using nested loops. With nested loops, we call the loop that is in thebody of the other loop, the "inner loop". The loop that contains the inner loop is the "outer loop". Openthe second file inside the outer loop:for line1 in file1:file2 = open(fname2)for line2 in file2:Python only lets you read the file once per open, so you need this order of instructions. Make sure yourreturn False is outside of both loops. Otherwise, you will only compare the first two lines of thefiles. Make sure you close the file that gets read repeatedly after the inner loop but still inside the outerloop.Here is some (more complete) pseudocode to get you started:open file 1for line1 in file 1open file 2for line2 in file 2:if line1 == line2:return Trueclose file 2return False

Write a function in python named "read_words" that declares a parameter for a filename and returns a collection of unique words in the file. Even though words.txt contains a single word per line, you should not assume that this is true of every file. For example, if the line is a sentence, you should split the line into individual words before storing each word in your collection. Handle any errors that occur by printing a detailed error message. Hint: the Python set works like Java's HashSet.
