[Solved] Identify the problem in this code: with open('file1.txt', 'r') as f1, open('file2.txt', 'w') as f2: data = f1.read() f2.write(data) | Python

Python - Context Managers

Identify the problem in this code:

with open('file1.txt', 'r') as f1, open('file2.txt', 'w') as f2:
    data = f1.read()
f2.write(data)

Af2.write(data) is outside the with block, so f2 is closed

Bf1.read() cannot be used with multiple files

CMissing exception handling for file operations

Df2.write() requires a string, data might be bytes

Step-by-Step Solution

Solution:

Step 1: Check indentation of f2.write(data)
It is outside the with block, so f2 is closed when this line runs.
Step 2: Understand consequence
Writing to a closed file causes a ValueError or IOError.
Final Answer:
f2.write(data) is outside the with block, so f2 is closed -> Option A
Quick Check:
Writing after with block closes file = C [OK]

Quick Trick: Keep file operations inside with block [OK]
