FindFailed Error when image is not on screen

Asked by MJ

for n in range(3):
#while (exists("1469038914742.png"),1):
#while True:
        if not exists("1469039051065.png"):
            click("1469038914742.png")
        else:
            click("1469042062223.png")
            click("1469038914742.png")

It spits out this error if image is not there how do i have the code end if image fails?

[error] script [ sikuli.sikuli3 ] stopped with error in line 5
[error] FindFailed ( 1469038914742.png: (23x34) in S(0)[0,0 1920x1080] E:Y, T:3.0 )

Thanks so much in advance

Learn Python try ... except .

https://docs.python.org/3/tutorial/errors.html#handling-exceptions

Here is how I handle it:

def try_click(our_image):
    try:
        click(our_image)
        return True;
    except FindFailed:
        return False

If this code finds image, it clicks it and returns True. If does not find image, it just returns False, no Click executed.

to handle this error (FindFailed) see:
http://sikulix-2014.readthedocs.io/en/latest/region.html#exception-findfailed

another option always is, to use exists:

        if not exists("1469039051065.png"):
            if exists"1469038914742.png"): click()
            else: pass #do something else
