In this video, we will write a Python program to Reverse the Content of a File using Stack. But before that we will first understand the concept of stack in brief.

What is Stack?

Stack is a linear data structure which follows a particular order in which operations are performed. The order maybe:
 

1. LIFO
2. FIFO

Stack is initialized & content of file is pushed one by one. Once the file is completely checked & all items are added, stack is popped until it becomes empty & content are restored in file in reverse order.
