error: global name 'Primary_OH' is not defined

[RickHawkins]

I am trying to run my program and when i get to this part of the program

I get the error that global name 'Primary_OH is not defined. Can someone look at my code and tell what i need to do to fix this.

Thanks

Your code would be a lot easier to trouble shoot if you paste it into the syntax highlighter rather than providing it as an image.  I don't see a reference to Primary_OH in the what you display, but I might be missing it. Somewhere in your code you call it and it should be in quotes is my guess...

Joe,

Thanks for the response. Line 77 is where the error is

Looks like line 74 is your problem. You are making a selection on what python thinks is a variable (since it's not quoted) but I don't see any other reference to Primary_OH.  Typically, you make a selection against a table view or a feature layer, and I don't see either of those as well.

[MichaelVolz]

Can you put a print statement in at line 73 and see what the result is?

[RickHawkins]

Michael,

i can put a print statement but what do you want me to have printed out? I think that the error is due to line 77 but not sure.

This is the error that i get

[MichaelVolz]

In your original post it said Primary_OH is not defined and now it says Primary_UG is not defined.

The print statement before the SelectLayerByAttribute call is just a troubleshooting technique to see what value is being passed if any.

[Javier_AntonioEscudero]

I realized there is a variable called my Map that is not really being used in your script.
Anyway, in the top of your script, try to define these variables as following:

from tkinter import *
from tkinter import messagebox
import Tkinter, arcpy

myMap = arcpy.mapping.MapDocument("C:/GISMAPS/LUS Map.mxd")
#myMap = arcpy.mapping.MapDocument("CURRENT")



# Referencing variables here -------------------------
Primary_OH_path = r"C:\<your_path>\<your_gdb.gdb>\Primary_OH" 
Primary_OH = arcpy.MakeFeatureLayer_management(Primary_OH_path, "Primary_OH")

Primary_UG_path = r"C:\<your_path>\<your_gdb.gdb>\Primary_UG"
Primary_UG = arcpy.MakeFeatureLayer_management(Primary_UG_path, "Primary_UG")

[JoeBorgione]

Line 77 & 85 are going to give you problems every time:

# line 77:

arcpy.SelectLayerByAttribute_management(Primary_OH, "", Expression)‍‍‍

# line 85:

arcpy.SelectLayerByAttribute_management(Primary_UG, "", "[FEEDERID] = '2050'")
‍‍‍‍‍‍‍

Primary_OH and Primary_UG are never defined as variables in your script; when python reads a string that is not within quotes, it treats that string as a variable.

 if x == 0:
    print(x)
    
Traceback (most recent call last):

  File "<ipython-input-1-ea8c3abaaaf7>", line 1, in <module>
    if x == 0:

NameError: name 'x' is not defined


x = 1  # value of x is now defined

 if x == 0:
    print('x equals zero')
else:
    print('Nope; x does not equal zero...')
    
Nope; x does not equal zero...‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍  # the result of the print() function...‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Javier,

I know about ..mxd files but do not know about .gdb files. Is that what you are telling me to put in the Primary_OH_path. Where would the .gdb be located? I do not see one when i search C: drive
