Find the bug in this SLA layer curing code:
layers = 4
for i in range(1, layers):
    print(f"Curing layer {i}")
ALoop misses curing the first layer
BRange function syntax is invalid
CPrint statement has wrong variable
DLayers variable should be a string
Step-by-Step Solution
Solution:
  1. Step 1: Analyze the range function parameters

    range(1, layers) starts at 1 and goes up to layers-1 (3), so layer 0 is skipped.
  2. Step 2: Understand the impact on layer curing

    The first layer (layer 0) is not cured because the loop starts at 1.
  3. Final Answer:

    Loop misses curing the first layer -> Option A
  4. Quick Check:

    Range start affects which layers are processed [OK]
Quick Trick: range(1, n) skips zero index layer [OK]
Common Mistakes:
MISTAKES
  • Assuming range(1, n) includes zero
  • Thinking print variable is wrong
  • Confusing variable types
