AttributeError: module 'time' has no attribute 'clock'

The 'clock' function has been removed from the 'time' module since Python 3.3. Instead, you can use the 'perf_counter' or 'process_time' functions depending on your use case. For example, to measure the time taken by a code block, you can do:

import time

start_time = time.perf_counter()

# code block to measure

end_time = time.perf_counter()

elapsed_time = end_time - start_time

print(f"Time taken: {elapsed_time:.6f} seconds")

This will output the time taken by the code block in seconds with up to 6 decimal places of precision.
