type system date (YYYYMMDD)

This is correct.

for exactly what you want:
type(strftime("%Y%m%d"))

Thanks Garrett Bartley, that solved my question.

Thank you very much for both of your comments!

Hallo I find the following error in my Sikuli IDE, can anyone help^^
[sikuli] [Error] source lineNo: 1
[sikuli] [Error] Traceback (innermost last):
  File "E:\Temp\sikuli-tmp3633998445704413443.py", line 1, in ?
NameError: strftime

guess you forgot
import time
before you used strftime() (since its line no 1 ;-)

time is the python module, that has to be imported first, to use the contained function strftime()

Hi RaiMan
Thanks your help,
It works as follow^^
import time
popup(time.strftime("%Y%m%d"))

looking at the row of comments, one get's the impression, that we were testing your ability, to bring things together ;-)
Yeah, you got it.

saying "from time import strftime" namespacing is done by python, so you can simply say strftime().

using only "import time" you have to tell python every time, to look at module time for strftime: time.strftime()

Thanks for your comment and have a nice TIME.

I tried to do the same, but it gives me this error:
  File "C:\Users\Nadesj\AppData\Local\Temp\sikuli-tmp7176782465826558881.py", line 15, in <module>
    type(strftime("%Y%m%d"))
NameError: name 'strftime' is not defined

this is how I defined it:
import time
type(strftime("%Y%m%d"))

@ Nadesj
the import time is nort needed (already done by Sikuli startup)

but you have to write (the module time is there, but you have to tell Python, that strftime is in module time additionally)
type(time.strftime("%Y%m%d"))

or you do it like mentioned in my comment above:
from time import strftime # this tells Python, that strftime comes from module time
type(strftime("%Y%m%d"))

Nice, thank you very much, I got it now.
I will have to learn some python before working with sikuli.

One problem yet, in the debug part it shows the right date,
in the software where I want it, it gives me this "éà&é&à" instead of 201210.

Must be a keyboard problem, i work with an Azerty keyboard.

sorry to waste your time, I found the solution in the forum,
I have to use paste. thx and sikuli is super.

Yes, keyboard problem. type() now only works correctly with the standard qwerty US layout.

use paste() instead - this works.

Besides learning some basic Python (really not much), it is a good idea to just read across the complete guide
http://sikuli.org/trac/wiki/reference-0.10

No problem.

Wasting time is always a decision and the responsibility of the one who is wasting his time ;-)

So you are always welcome with your questions - but you have to live with the answer or with the fact, that no one answers ;-)
