Python - File Reading and Writing Strategies

What will be the output of this code snippet reading a file in fixed-size chunks?

with open('sample.txt', 'r') as f:
    while True:
        data = f.read(4)
        if not data:
            break
        print(data, end='-')

ARaises an error due to incorrect read size

BPrints the entire file content at once

CPrints nothing because of an infinite loop

DPrints the file content in 4-character chunks separated by '-'

Step-by-Step Solution

Solution:

Step 1: Read fixed-size chunks
The code reads 4 characters at a time from the file until no data is left.
Step 2: Print chunks with separator
Each chunk is printed followed by a '-', so output shows file content in 4-char segments separated by '-'.
Final Answer:
Prints the file content in 4-character chunks separated by '-' -> Option D
Quick Check:
Reads 4 chars repeatedly until EOF [OK]

Quick Trick: Read fixed-size chunks and print until empty [OK]
