AttributeError: module time has no attribute clock

The error message indicates that the module "time" does not have an attribute called "clock". This is because the attribute "clock" was removed in Python 3.3 and replaced with "perf_counter" or "process_time" depending on the use case.

To fix this error, you can replace "time.clock()" with either "time.perf_counter()" or "time.process_time()" based on your specific use case.

For example, if you were using "time.clock()" to measure the elapsed time of a program or function, you can replace it with "time.perf_counter()" as follows:

import time

start_time = time.perf_counter()

# Code to be timed here

end_time = time.perf_counter()
elapsed_time = end_time - start_time
print("Elapsed time: ", elapsed_time)

Alternatively, if you were using "time.clock()" to measure CPU time consumed by a program or function, you can replace it with "time.process_time()" as follows:

import time

start_time = time.process_time()

# Code to be timed here

end_time = time.process_time()
elapsed_time = end_time - start_time
print("Elapsed CPU time: ", elapsed_time)

Note that "perf_counter" measures wall-clock time, while "process_time" measures CPU time consumed by the current process. Choose the appropriate method based on your use case.
