ctime

Returns the number of CPU seconds used.

Synopsis

ctime( )

Return Value

The number of CPU seconds used so far by the program.

Example

The CPU time needed to compute

\[\textstyle\sum_{k=0}^{1,000,000} k\]

is obtained and printed. The time needed is, of course, machine dependent. The CPU time needed will also vary slightly from run to run on the same machine.

from __future__ import print_function
from pyimsl.math.ctime import ctime

sum = 0
for k in range(1, 1000001):
    sum += k
time = ctime()
print("sum = ", sum)
print("time = ", time)

Output

sum =  500000500000
time =  0.448164
