1 point
dt = f,readlines(); print(dt[3])
dt=f.read(4) ; print(dt[3])
dt=f.readline(4) ; print(dt[3])
All Of These

Answer 1

To read 4th line from text file,

dt = f.readlines();print(dt[3])

Explanation:

The readline () function is used to read a text line.

Answer 2

• Each line is being returned as a string.
• We have noticed \n at the end of each line.
• This is a line return character which indicates the end of a line.
• f.readlines() actually reads in the whole file and splits it into a list of lines.
• So for large files, this can be of memory intensive.

Therefore, to read the 4th line from a text file, we use  the method

             dt = f.readlines(); print(dt[3])
