Consider this code snippet:

lock.acquire()
shared_list.append(1)
lock.release()
print(len(shared_list))

What is the output if multiple threads run this code simultaneously with proper locking?

ALength may be incorrect due to race condition

BLength will always be 1

CLength will be equal to the number of threads

DCode will throw an error

Step-by-Step Solution

Solution:

Step 1: Understand locking effect
Lock ensures only one thread appends at a time, preventing race conditions.
Step 2: Predict output
Each thread appends 1, so length equals number of threads.
Final Answer:
Length will be equal to the number of threads -> Option C
Quick Check:
Proper locking = correct list length [OK]

Quick Trick: Locks ensure correct shared list updates [OK]
