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.
