[Solved] Given this code snippet, what will be the output? from smbus2 import SMBus bus = SMBus(1) try: bus.write_byte_data(0x50, 0x02, 0x10) print("Command sent") except Exception: print("Failed to send") | Raspberry Pi

Raspberry Pi - I2C Communication

Given this code snippet, what will be the output?

from smbus2 import SMBus
bus = SMBus(1)
try:
    bus.write_byte_data(0x50, 0x02, 0x10)
    print("Command sent")
except Exception:
    print("Failed to send")

ACommand sent

BFailed to send

CNo output

DSyntax error

Step-by-Step Solution

Solution:

Step 1: Understand try-except block
If write_byte_data succeeds, it prints "Command sent"; if it fails, it prints "Failed to send".
Step 2: Assume normal device connection
With device connected and no error, the try block runs successfully.
Final Answer:
Command sent -> Option A
Quick Check:
Successful write triggers "Command sent" [OK]

Quick Trick: Try block runs if no error, printing success [OK]
