Write a pythonprogram that reads in a Python source code file and counts the occurrence of each keyword and eachidentifier (variables, class and method names) in the file using three dictionaries: one for keywords and one forvariables, and one for integer (e.g. 12,44) and string literals (e.g. “aba”, “ali”) Your program should prompt theuser to enter the Python source code filename.Keywords in Python programming language:False class finally is return None continue for lambda tryTrue def from nonlocal while and del global not with as elifif or yield assert else import pass break

- (5) Write a function called copy_even_lines() that takes two strings (filenames) as input parameters and copies every other line from the first file into the second. That is, counting from 0, it copies the 0th line, the 2nd line, the 4th line, etc. from the first file to the second file. You may assume that both files exist. (6) Write a python program that asks the user for two filenames and calls your function copy_even_lines() from (5) using those two filenames. If one or more files do not exist, your program must handle the exception by repeating the prompts until valid filenames are entered.arrow_forwardUse the Bash shell for the completion of this project. Develop a shell scripting application that allows the user to perform some advanced mathematical operations. Your application should allow the user to perform these tasks: Task 2: Find the term of any linear sequence given by the rule Term = a * n + b, where a and b are integers specified by the user and n is a positive integer and print them in order (for example if the user inputs a=3, b=-4, the first few terms that should be printed are -1, 2, 5, 8, 11…). The user also will specify how many terms the program should print. In addition, the program should print the sum of terms found and a count of how many odd terms were found.arrow_forwardIn C++, Query the user for the name of a file.
