Repeat Exists (Avoid Writing Log Errors) Python

[M_Schofer_1111]

This is a script I have pared down in the utter hope I can make my slf clear.

I an using different users in loops and some elements do not exist for certain users. 

I am using exists to see if an item exists,

If it doesn't exist, it writes errors to the log.--I dont want this.

Documentations says to use this methodology.

if (Sys.Process("notepad").WaitWindow("#32770", "About Notepad", 1, 5000).Exists):
  # Notepad is running
else:
  # Notepad is not running

My code snippet

def a1():
try:
# # finds the link and verifies it exists on page
# myLinkXPath = "//a[text()='Purchase Inquiry']"
# myTestLink = JCCommon.verify_link(myLinkXPath)
# myTestLink.Click()
#
browser = Aliases.browser
CurrPage = browser.Page("*")
CurrPage.Wait()

myPT = CurrPage.FindElement("//font[.='Purchase Types']")      

if myPT.Exists:                                              -This works or throws an error if it doesn't exist.
Log.Message("I am the Rain Queen")

if myPT.WaitWindow("#32770","Wait Window",-1,10000).Exists: Per Documentation however this doesn't work. 
Log.Message("Found Purchase Type Header")
else:
Log.Message('Not Found Purchase Type')
except Exception as e:
myErrMessage = JCCommon.capture_error(e)
Log.Error(myErrMessage)

"Documentations says to use this methodology" - which document are you referring too?

So you output a message "I am the Rain Queen" if you have found the element "Purchase Types" in your web page?

You are then waiting for a window or dialog to appear named "Wait Window", which doesn't appear? So it performs the code for "Not Found Purchase Type". I don't understand what except does?

Use the code editor to attach your code, as it keeps the format

I think the call to FindElement is probably the one that is logging the error.  You can use other alternatives such as FindElements and then get a list of elements (list would contain nothing in this case) and go from there.      

I do agree that when FindElement cannot find something it logging an error is problematic, and it would be good if they had an optional parameter to log an error or not.

Thank for the reminder on the code editor. Didn't know anything about that.

I have a large script that loops through many user types.

And for certain user's objects are not there, 

So I am using exists to find the objects, and then for other users it writes an error. (Which I would prefer not to happen)

It is actually discussed in the forum here.
