A student launches the Python interpreter from his home directory. His home directory contains another directory called 'mydir', and 'mydir' contains two files called 'foo' and 'bar'. The home directory does not contain any files, only other directories. What will happen when he writes the following code at the Python prompt: >>> import os >>> filenames = os.listdir('mydir') >>> f= open(filenames[0]) ===================================================================================== A variable f representing a file object will be created, and the first file in the directory 'mydir' will be opened for writing in text mode. An error will be produced stating that the file to be opened does not exist. An error will be produced stating that filename is not subscriptable. A variable f representing a file object will be created, and the first file in the directory 'mydir' will be opened.

In C++ Implement a simple version of the linux grep command in C++. grep - Looks through a file, line by line, trying to find a user-specified search term in the line. If a line has the word within it, the line is printed out, otherwise it is not. Use the system calls open(), getline(), close(). Requirements (examples run from. terminal) Your program grep is always passed a search term and zero or more files to grep through (thus, more than one is possible). It should go through each line and see if the search term is in it; if so, the line should be printed, and if not, the line should be skipped. [terminal]$ ./grep ! main.cpp main2.cppcout << "Hello, World!";cout << "Programming is great fun!"; The matching is case sensitive. Thus, if searching for world, lines with World will not match. Lines can be arbitrarily long (that is, you may see many many characters before you encounter a newline character, \n). grep should work as expected even with very long lines. For…

Write a program called asyncFileCount.js that prints the number of files with a given extension in a given directory. The first argument will be the path to the directory we want to filter on (e.g. /path/to/dir/') and a file extension to filter by as the second argument. For example, if you get '.txt' as the second argument then you will need to filter the list to only files that end with .txt Below are some example runs: An example run would be: node asyncFileCount.js . .js Another example run would be: node asyncFileCount.js /Users/jalirani/Desktop .docx
