CBSE 2025, Set 4, Q29 (a)

Question

Write a Python function that displays all the lines containing the word 'vote' from a text file "Elections.txt". For example, if the file contains :

> In an election many people vote to choose their representative.
> The candidate getting the maximum share of votes stands elected.
> Normally, one person has to vote once.
> The process of voting may vary with time and region.

Then the output should be :

> In an election many people vote to choose their representative.
> Normally, one person has to vote once.

The correct answer is Subjective. Here is the Python function to display all lines containing the exact word "vote": ```python def display_vote_lines(): try: with open("Elections.txt", "r") as file: lines = file.readlines() for line in lines: # Using .split() ensures we match the exact word 'vote' # rather than substrings like 'votes' or 'voting' words = line.split() if "vote" in words: print(line.strip()) except FileNotFoundError: print("File Elections.txt not found.") # --- Example Usage --- # display_vote_lines() ``` **Explanation:** 1. **`open("Elections.txt", "r")`**: Opens the text file in read mode. 2. **`file.readlines()`**: Reads all lines from the file into a list. 3. **`line.split()`**: Splits the current line into a list of individual words. This is crucial because a simple `"vote" in line` check would incorrectly match words like "votes" and "voting". 4. **`print(line.strip())`**: Removes the trailing newline character `
` from the file line so extra blank lines aren't printed.
