Let's analyze the code step by step to determine the expected output.
Code breakdown:
Initialization:
data = {'one': 'two', 'two': 'three', 'three': 'one'}
res = data['three'] # res = 'one'
Loop execution:
for _ in range(len(data)): # len(data) = 3
res = data[res]
The loop runs 3 times (since len(data) = 3).
Iterations:
First iteration: res = data[res] = data['one'] = 'two'
Second iteration: res = data[res] = data['two'] = 'three'
Third iteration: res = data[res] = data['three'] = 'one'
Final value of res: After 3 iterations, res is 'one'.
Output:
print(res) # Outputs 'one'
Expected Output:
one
