Python - File Handling Fundamentals

You want to safely read a file named log.txt and automatically close it after reading. Which code snippet correctly does this using Python's best practice?

Afile = open('log.txt', 'r') content = file.read() file.close()

Bopen('log.txt', 'r').read()

Cfile = open('log.txt', 'r') content = file.read()

Dwith open('log.txt', 'r') as file: content = file.read()

Step-by-Step Solution

Solution:

Step 1: Understand safe file handling
Using with statement ensures the file is automatically closed after the block finishes, even if errors occur.
Step 2: Compare options
file = open('log.txt', 'r') content = file.read() file.close() requires manual close, C misses close, D reads but does not save content or close explicitly.
Final Answer:
with open('log.txt', 'r') as file: content = file.read() -> Option D
Quick Check:
Use with statement for auto-close [OK]

Quick Trick: Use with open(...) as file for automatic closing [OK]

Common Mistakes:

Forgetting to close file manually
Not using with statement for safety
Ignoring file object after open()
