Python | time.clock() method
Time module in Python provides various time related functions.
time.clock() method of time module in Python is used to get the current processor time as a floating point number expressed in seconds.
As, Most of the functions defined in time module call corresponding C library function. time.clock() method also call C library function of the same name to get the result. The precision of returned float value depends on the called C library function.

Note: This method is deprecated since Python version 3.3 and will be removed in Python version 3.8. The behaviour of this method is platform dependent.
Syntax: time.clock()
Parameter: No parameter is required.
Return type: This method returns a float value which represents the current processor time in seconds.
Code #1: Use of time.clock() method to get current processor time
# Python program to explain time.clock() method # importing time moduleimport time # Get the current processor# time in secondspro_time = time.clock() # print the current # processor timeprint("Current processor time (in seconds):", pro_time) |
Current processor time (in seconds): 0.042379
Code #2: Use of time.clock() method to get current processor time
# Python program to explain time.clock() method # importing time module import time # Function to calculate factorial # of the given number def factorial(n): f = 1 for i in range(n, 1, -1): f = f * i return f # Get the current processor time# in seconds at the # beginning of the calculation # using time.clock() method start = time.clock() # print the processor time in seconds print("At the beginning of the calculation") print("Processor time (in seconds):", start, "\n") # Calculate factorial of all # numbers form 0 to 9 i = 0fact = [0] * 10; while i < 10: fact[i] = factorial(i) i = i + 1 # Print the calculated factorial for i in range(0, len(fact)): print("Factorial of % d:" % i, fact[i]) # Get the processor time# in seconds at the end # of the calculation # using time.clock() method end = time.clock() print("\nAt the end of the calculation") print("Processor time (in seconds):", end) print("Time elapsed during the calculation:", end - start) |
At the beginning of the calculation Processor time (in seconds): 0.03451 Factorial of 0: 1 Factorial of 1: 1 Factorial of 2: 2 Factorial of 3: 6 Factorial of 4: 24 Factorial of 5: 120 Factorial of 6: 720 Factorial of 7: 5040 Factorial of 8: 40320 Factorial of 9: 362880 At the end of the calculation Processor time (in seconds): 0.034715 Time elapsed during the calculation: 0.0002050000000000038
