- If a file is opened for writing but it already contains data, it will append to the file. overwrite the file. delete the file. throw an error.Assignment: Exception Handling and Text 10 Problem Statement: Write a program that reads a file named "input.txt" that contains integers separated by whitespace (space, tab, or newline). The program should calculate the sum of all the integers in the file, ignoring any non-numeric values. Requirements: The program should define a class named "FileSumCalculator". The class should have a method named "calculateSum" that takes a file path as a parameter and returns the sum of all the integers in the file. The method should handle any exceptions that might occur during the file reading and sum calculation. The program should print the sum of all the integers in the file to the console. Examples: 1. If the contents of the "input.txt" file are: 123 4 five 67 The program should print: Sum: 23What type of exception does a program raise when it tries to open a nonexistent file?
- fname=input("Enter a file's name: ") with open(fname, 'r') as fh: for line in fh: print(line) Criteria to complete the above snippet: 1)Code will keep looping until the user enters an existing file name. 2) need to use exception with [Error 7] as the message 3)need to catch the exception so the program does not crash 4) close the program after reading contents of the file and print contents to the screen 5)create a test fileTrue/False 10. The process of associating a file with an object in a program is called "reading" the file.Files Class Activity Write a program to write your first name (hard coded) to the screen and possibly to a file whose name is passed into the program from the command line. It can be written in upper or lower case or mixed case as the default. Usage: writer [-f filename] If the -f option is included with a filename, then create a file with that name or overwrite a previously existing file and write your name in on the first line. If the -f option is not included, then only write your name to the screen followed by a newline. Use a copy of the original getopt to parse the command line. Be sure to test whether a file open succeeds or not and close any file you open when done.
- What are some common techniques for handling exceptions when reading a file?C2- Write a Python program that reads the contents of a file named ‘Book.txt’ (you must write exception handling if the file doesn’t exist) The program should also determine and print the following: The number of words in the file The number of distinct words (without repetition) The number of uppercase letters in the file The number of lowercase letters in the file The number of digits in the file The number of whitespace characters in the fileThe function fopen return NULL when: An error occurred while opening the file. An error occurred while reading the file. An error occurred while closing the file. An error occurred while compiling the file.
