On either platform the default timer functions measure wall clock time not the cpu time.
Timeit timeit wall clock.
On windows time clock has microsecond granularity but time time s granularity is 1 60th of a second.

The difference in default timer function is because on windows clock has microsecond granularity but time s granularity is 1 60th of a second.
All we did was to pass the code as a string and specify the number of iterations to the timeit timeit function.
The timeit and time magics.
Timeit method is available with python library timeit.
It is used to get the execution time taken for the small code given.
On either platform default timer measures wall clock time not the cpu.
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.
On unix time clock has 1 100th of a second granularity and time time is much more precise.
The timeit and time magics.
Now let us look at a way to use this amazing library to compare two functions.
On windows time clock has microsecond granularity but time time s granularity is 1 60th of a second.
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 unix clock has 1 100th of a second granularity and time is much more precise.
Python3 m timeit join str n for n in range 100 10000 loops best of 5.
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.
On either platform the default timer functions measure wall clock time not the cpu time.
The library runs the code statement 1 million times and provides the minimum time taken from the set.
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.
