 here is the description below “w” opens a file for writing only. overwrites the file if the file exists. if the file does not exist, creates a new file for writing.

 use r+, w+ or a+ to perform both read and write operations using a single file object.

 fp.size has not been implemented.

 close() is a method of the file object.

 it gives the current position as an offset from the start of file.

 os.rename() is used to rename files.

 the details of the program can be addressed before the overall design too.

 during a python program execution, there are as many as three namespaces – built-in namespace, global namespace and local namespace.
