Carefully analyze the following Python program. The purpose of the program is to replace all occurrences of the word "Bombay" with the word "Mumbai" in a text file named "maharashtra.txt". However, certain parts of the code are missing and have been labeled as Task A, Task B, Task C and Task D. Complete the missing statements so that the program functions correctly. The file must be opened only once in a mode that allows both reading and writing.
try:
_____________ as File: # Task A
Text = ______ # Task B
NewText = Text.replace("Bombay", "Mumbai")
File.______ # Task C
______ # Task D
File.truncate()
except:
print('File I/O Error!')Questions:
(A) Write the missing statement for Task A to open the file in both read and write mode.
(B) Write the missing statement for Task B to read the entire content of the file and store it in the identifier Text.
(C) Write the missing statement for Task C to move the file pointer to the beginning of the file.
(D) Write the missing statement for Task D to write the modified content stored in NewText back into the file.
Show answer & explanation
(A) Task A (Open file in read + write mode):
open("maharashtra.txt", "r+")
Reason: The r+ mode allows both reading and writing without opening the file multiple times.
(B) Task B (Read complete content):File.read()
Reason: Reads the entire file content and stores it in Text.
(C) Task C (Move file pointer to beginning):File.seek(0)
Reason: Resets the file pointer to the start so that new content overwrites from the beginning.
(D) Task D (Write modified content):File.write(NewText)
Reason: Writes the updated text (with “Bombay” replaced by “Mumbai”) back into the file.
