On unix clock has 1 100th of a second granularity and time is much more precise.
Timeit timeit wall clock.
Time clock has microsecond granularity but time time s granularity is 1 60th of a second.
On unix time clock has 1 100th of a second granularity and time time is much more precise.
On either platform the default timer functions measure wall clock time not the cpu time.
On either platform the default timer functions measure wall clock time not the cpu time.
It is used to get the execution time taken for the small code given.
The wall clock time is also called elapsed or running time.
On unix time clock has 1 100th of a second granularity and time time is much more precise.
Compared to the cpu time the wall clock time is often longer because the cpu executing the measured program may also be executing other program s instructions at the same time.
The timeit and time magics.
Python3 m timeit join str n for n in range 100 10000 loops best of 5.
For this example let us compare two sorting functions one is a simple bubble sort and the other is the python s built in sorted function.

Another important concept is the so called system time which is measured by the system clock.
30 2 usec per loop python3 m timeit join str n for n in range 100 10000 loops best of 5.
On windows time clock has microsecond granularity but time time s granularity is 1 60th of a second.
27 5 usec per loop python3 m timeit join map str range 100 10000.
On windows time clock has microsecond granularity but time time s granularity is 1 60th of a second.
The timeit and time magics.
The difference in default timer function is because on windows clock has microsecond granularity but time s granularity is 1 60th of a second.
Now let us look at a way to use this amazing library to compare two functions.
On either platform default timer measures wall clock time not the cpu time.
On unix time clock has 1 100th of a second granularity and time time is much more precise.
Timeit method is available with python library timeit.
The library runs the code statement 1 million times and provides the minimum time taken from the set.
