Calculate Field not working when iterating through a list of feature classes

AlfredBaldenweck

Hi all,

I'm trying to calculate the same field in multiple feature classes in a list.

The first time it runs after opening Pro, it works great. However, each time after that, it will calculate the field for the first feature class in the list and ignore the rest.

Does anyone have any ideas as to what might be causing it?

 

 

FCList= [FC1, FC2]
for FC in FCList:
    arcpy.management.CalculateField(FC, 'SampleField', '"Hello world"', 'ARCADE')

 

 

 

Edit: 

My current best guess is that later in the script I delete the field that's being calculated, and that's what's causing it to freak out. Does anyone have any ideas for how to prevent that from happening? 

 

FCList= [FC1, FC2]
for FC in FCList:
    arcpy.management.CalculateField(FC, 'SampleField', '"Hello world"', 'ARCADE')

#code
#code
'''This is where the problem is, I think?'''
arcpy.management.DeleteField(FC, 'SampleField')

Not showing enough code to have an idea as to what is in the FCList (what is FC1 equal to, etc.).

So, if you use the following code, do you see it listing ALL the feature classes?

Once you get it listing the appropriate FC's, then you can put the CalculateField back in there.

 

FCList= [FC1, FC2]
for FC in FCList:
    print(FC.name)
