🔒 How to get average of end times

[scarlet quartz]

import time
import random

for x in range (6):
    start = time.time()
    print (random.randrange(1,1000000000))
    end = time.time()
    print(f"Time taken to run the code was {end - start} seconds")

I want to get the average of the end times, how do i add the end time to a variable after every run?

• Ask your Python question, not if you can ask or if there's an expert who can help.
• Show a code sample as text (rather than a screenshot) and the error message, if you've got one.
• Explain what you expect to happen and what actually happens.

append to a list and then divide it by its length

[velvet otter]

import time
import random

durations = []

for x in range(6):
    start = time.time()
    print(random.randrange(1, 1000000000))
    durations.append(time.time() - start)

if durations:
    print(f"Averge time taken to run the code was {sum(durations) / len(durations)} seconds")

[scarlet quartz]

so hypothetically is there any way to lower the duration

Im getting an average of about 1.3 secs

just curious if better hardware would make that time faster

Averge time taken to run the code was 8.463859558105469e-06 seconds

1.3 seconds seems a bit slow. What hardware, what Python version?

That's using offby1's code above on Python 3.10.6.

[scarlet quartz]

pycharm hwo do i check version

[gritty smelt]

There should be some dropdown about selecting a Python. It should show what's current.

But 1.3s vs 8us is a huge difference.

[scarlet quartz]

3.8

[gritty smelt]

>>> import sys
>>> sys.version_info
sys.version_info(major=3, minor=10, micro=6, releaselevel='final', serial=0)

Maybe random.randrange got a reimplementation.

Hmm, 3.8 here:

349534162
470901265
280833842
277962006
268003026
245916348
Averge time taken to run the code was 9.338061014811197e-06 seconds

Essentially the same.

Can you show the code the 1.3s came from?

[scarlet quartz]

so u said 1 was slow how is 9 not slower

[gritty smelt]

You said 1.3 seconds. This is in microseconds.

[scarlet quartz]

ohh

[gritty smelt]

Care to show the code and rerun it?

[scarlet quartz]

thats all it is

import time
import random

durations = []

for x in range(6):
    start = time.time()
    mian=(random.randrange(1, 1000000000))
    durations.append(time.time() - start)

if durations:
    print(f"Averge time taken to run the code was {sum(durations) / len(durations)} seconds")```

[gritty smelt]

Can you run it and copy/paste the output?

[scarlet quartz]

Averge time taken to run the code was 2.9007593790690103e-06 seconds

[gritty smelt]

That's more like it.

[scarlet quartz]

yah i didn't know that was microseconds

[gritty smelt]

e-06

[scarlet quartz]

yah that makes sense

how many micro in a second

[gritty smelt]

1000000

10^6, a million

[scarlet quartz]

ok cool

[gritty smelt]

Same 6 as in the e-06.

[scarlet quartz]

so 2 millionth of a second

[gritty smelt]

Closer to 3.

[scarlet quartz]

yah got it cool

[gritty smelt]

The number of iterations is small enough that's you'll see some variance.

[scarlet quartz]

yah i was running it a thousand times and getting closer to the same number

[gritty smelt]

There's a timeit module in the stdlib for running code to measure its average time, it is common to ask it to run the code many times for the average.

thx for the help
