This 3D printer script snippet is intended to set the nozzle temperature to 230°C for ABS filament, but it has an error:

nozzle_temp = "230C"
if nozzle_temp > 220:
    print("Nozzle temperature set for ABS")
else:
    print("Temperature too low")

What is the error and how to fix it?

ANo error; code runs fine

BError: Missing colon after if; fix by adding colon

CError: Print statement syntax; fix by adding parentheses

DError: Comparing string with int; fix by removing "C" and converting to int

Step-by-Step Solution

Solution:

Step 1: Identify data type mismatch
nozzle_temp is a string "230C", but compared to integer 220, causing a type error.
Step 2: Fix by converting string to int
Remove "C" and convert to integer: nozzle_temp = int("230") to allow numeric comparison.
Final Answer:
Error: Comparing string with int; fix by removing "C" and converting to int -> Option D
Quick Check:
String vs int comparison causes error [OK]

Quick Trick: Compare numbers, not strings with units [OK]
