Question

What is a file's read position? Initially, where is the read position when an input file is opened?

Solution Preview

Read position is a special value to mark the location of the next item that will be read from the file. The location has been read when the file is opened using 'r' mode. The read position is internally maintained for that "input file".

Initially, the location of the read position is set at the beginning of the input file when the file is opened.

The following code is used to demonstrate the read position in a file:

#Function main

def main():

#Open an input file for reading

fileobject=open('Names.txt','r')

#Reading three lines from file

line1=fileobject.readline()

line2=fileobject.readline()

line3=fileobject.readline()

#Close the file

fileobject.close()

#Print the data

print(line1)

print(line2)

print(line3)

#Call the main function

main()
