simple for loop? - gr3yali3n - Sep-21-2020

how would I write a for loop to take 15 screenshots under different names with pyautogui or any other way? the pyautogui just replaces the same picture over and over.
I thought I had these for loops understood but apparently not , I still have a lot to learn.
I have another for loop question but ill leave this to one question.

ive tried

for pic in range(15):
    pyautogui.screenshot('/Users/user/Desktop/screenshots/picture.png')

This will increment picture1..2..3..4 etc

for pic in range(15):
    pyautogui.screenshot(f'/Users/user/Desktop/screenshots/picture{pic}.png')

Here's another technique:

import os

filelist = os.listdir("/media/Avocet/Python/")
for filename in filelist:
    print(filename)

The output (on my computer) is:

Quote:testing.py
CheckTest.py
tkinter.pdf
CounterTest.py
ForTest.py
passweird.py
alarming.py
Colors.odt
PythonNotes.odt
hoot.wav
says.wav

I imagine your screenshot line will look something like this:

pyautogui.screenshot(f'/Users/user/Desktop/screenshots/' + filename)

One advantage of this technique is that it works with whatever files exist. Disclaimer, I didn't test the screenshot part.

@Mik3e, I think you misunderstood OP request. They want to take 15 screenshots and save each one under different name. They don't try to list files already existing in a folder.
