Q. What is the output of following code fragment? Explain.

out = open("output.txt", "w")

out.write("Hello, world! \n")

out.write("How are you?")

out.close()

print (open("output.txt").read())

Answer :-

The output will be:

Hello, world!

How are you?'

The first line of the code is opening the file in write mode; the next two lines write text to the file. The last line opens the file and from that reference reads the file-content. Function file() does the same as that of open(). Thus file("output.txt") will give the reference to open file, on which read() is applied.
