- Write a program named PullPDF2 to pull text information from a PDF document. Your program should include two functions. Pull the data from the pdf file USCensus.pdf into a text file called USCensus_Output.txt. The file USCensus.pdf exists in the PythonFile directory of your VCASTLE Pod. Take a screenshot of your completed program and another of your output. Your output may be a screen shot of the last 20 lines of the USCensus_Output.txt file. Show the title bar of the code window, and include the VCASTLE system date and time in the lower right hand corner of the screen.arrow_forwardThe following project should be done in C++ language: Write a function (module) that reads the contents of a file named Char.txt (you will have to create this file on notepad or any other text editor and write a sentence of your choice. Your sentence should include upper case, lower case, and numbers. Keep in mind you need to submit this file as well) and determine the following: The number of uppercase letters in the file . The number of lowercase letters in the file The number of digits in the file The total number of characters in your sentence. Upon finishing the task, program will ask the user if they would like to read the same file again and the program will re-start (you need to utilize a loop to do so) should the user prompt the program with 'Y'. Prompts and Output Labels. There are no prompts-- nothing is read from standard keyboard, just from the file Character.txt. Each of the numbers calculated is displayed on a separate line on standard output, preceded by the following…arrow_forwardpython Write a function that reads in a text file, and counts the number of times each word occursin the file. Then print the words alphabetically with its corresponding count. Each word willbe separated by a space or newline, but there is no guarantee that each word will be on aseparate line.arrow_forward
- in c with commentsarrow_forwardI need this code to pythonarrow_forwardWrite 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.arrow_forward
- Write a Python function ‘AVGCSV’ that reads a .csv file that includes ‘n’ rows and ‘m’ columns, it calculates the average of each row and writes it at the end of the row, and it calculates the average of each column and writes it at the end of the column. The function should modify the .csv file and save it after adding all the averages.arrow_forwardGiven the following code, I need help correcting it to follow these instructions using python (the csv file contains the following info...)
