The wall clock time is also called elapsed or running time.
Timeit timeit wall clock.
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.
The library runs the code statement 1 million times and provides the minimum time taken from the set.
30 2 usec per loop python3 m timeit join str n for n in range 100 10000 loops best of 5.
On unix time clock has 1 100th of a second granularity and time time is much more precise.

It is used to get the execution time taken for the small code given.
On unix time clock has 1 100th of a second granularity and time time is much more precise.
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 default timer measures wall clock time not the cpu time.
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.
All we did was to pass the code as a string and specify the number of iterations to the timeit timeit function.
Timeit method is available with python library timeit.
On unix clock has 1 100th of a second granularity and time is much more precise.
The timeit and time magics.
The timeit and time magics.
Python3 m timeit join str n for n in range 100 10000 loops best of 5.
On either platform the default timer functions measure wall clock time not the cpu time.
27 5 usec per loop python3 m timeit join map str range 100 10000.
Now let us look at a way to use this amazing library to compare two functions.
Time clock has microsecond granularity but time time s granularity is 1 60th of a second.
On windows time clock has microsecond granularity but time time s granularity is 1 60th of a second.
The following example shows how the command line interface can be used to compare three different expressions.
On either platform default timer measures wall clock time not the cpu.
