Python - Structured Data Files
Identify the issue in this code snippet that attempts to read a CSV file:
import csv
with open('data.csv', 'r') as f:
    reader = csv.reader(f)
    for row in reader:
    print(row)
AThe file is opened in read mode instead of write mode.
BThe print statement inside the for loop is not properly indented.
CThe csv.reader function requires a delimiter argument.
DThe file object should be opened with newline=''.
Step-by-Step Solution
Solution:
  1. Step 1: Check the for loop indentation

    The print statement must be indented inside the for loop to execute for each row.
  2. Step 2: Verify file mode

    The file is correctly opened in read mode ('r') for reading CSV data.
  3. Step 3: Confirm csv.reader usage

    csv.reader does not require a delimiter argument unless a non-default delimiter is used.
  4. Step 4: newline parameter

    While recommended for writing, newline='' is not mandatory for reading CSV files.
  5. Final Answer:

    The print statement is not indented properly inside the for loop. -> Option B
  6. Quick Check:

    Indentation error in loop body [OK]
Quick Trick: Ensure loop bodies are indented correctly [OK]
