Write a sequence of statements that create a file named "greeting" and write a single line consisting of "Hello, World!" to that file. Make sure that the line has been flushed to the file and that any system resources used during the course of running these statements have been released.

The solution code is written in Python 3 as below:

outfile = open ("greeting. txt", "w") outfile. write ("Hello World") outfile. close ()

Explanation:

To create a simple text file in Python, we can use Python built-in function, open (). There are two parameters needed for the open () function,

the file name and a single keyword "w". "w" denote "write". This keyword will tell our program to create a file if the file doesn't exist.

The statement open ("greeting. txt", "w") will create a text file named "greeting. txt" (Line 1)

To fill up the content in the greeting. txt, we use write () method. Just include the content string as the argument of the write () method. (Line 2)

At last, we use close () method to close the opened file, outfile. This will release the system resource from the outfile.
