Answer:

The answer to this question is option "C".

Explanation:

The stack is part of the data structure. In this stack perform two operations that are "push and pop". The push function is used to push(insert) and pop function is used to pop(delete) elements on the stack. It follows the LIFO process that stands for last in first out.

  • In this code, firstly we insert three elements on the stack that is "a, b and c".
  • Then, we insert two elements on the stack that is "d and e", in this element store in the upper part of the stack and then we call pop function two times.
  • In first time, the call will remove elements e and the second time it will remove element d.

That's why the answer is option "C".

The readline method reads text until an end of line symbol is encountered, how is an end of line character represented
zhannawk [14.2K]

Answer:

\n

Explanation:

readline() method is used to read one line from a file. It returns that line from the file.    

This line from the file is returned as a string. This string contains a \n at the end which is called a new line character.

So the readline method reads text until an end of line symbol is encountered, and this end of line character is represented by \n.

For example if the file "abc.txt" contains the lines:

Welcome to abc file.

This file is for demonstrating how read line works.

Consider the following code:

f = open("abc.txt", "r")  #opens the file in read mode

print(f.readline()) # read one line from file and displays it

The output is:

Welcome to abc file.    

The readline() method reads one line and the print method displays that line.
