Populating a Dictionary with an Update Cursor "Typeerror: 'Dict' Object Is Not Callable"

Question

I'm getting the following error "Type Error: 'dict' object is not callable", with the code below:

import arcpy

def printDict(dictionary, printCount=False):
    for key in dictionary:
        arcpy.AddMessage(key + ": " + dictionary[key])
    if printCount is True:
        arcpy.AddMessage(str(len(dictionary)))

pld3GDB = 'C:\\Users\\bro81520\\Documents\\ArcGIS\\PLDV3_SPC_ODN_315_25Sep\\PLDV3_SPC_ODN_315_25Sep.gdb\\WO_HIERARCHY'
fdaAREA = 'C:\\Users\\bro81520\\Documents\\ArcGIS\\Default.gdb\\FDA_AREA'

d = dict()  # VENDOR_WO_ID : NFID

fields1 = ['VENDOR_WO_ID', 'NFID', 'ISFDA'] 
with arcpy.da.SearchCursor(pld3GDB, fields1) as cursor:
    for row in cursor:
        if row[2] == "Y":
            d[row[0]] = row[1]

# print dictionary
printDict(d, printCount=True)

fields2 = ['bv_workorderid', 'bv_nfid']
with arcpy.da.UpdateCursor(fdaAREA, fields2) as cursor:
    for row in cursor:
        if row[0] in d:
            row[1] = d[row[0]]
            cursor.updateRow(row)           

I've looked at the following resources, but haven't deciphered exactly what is wrong: https://stackoverflow.com/questions/41605525/typeerror-dict-object-is-not-callable-while-using-dict

Answer 1

I suspect somewhere along the way, the built-in dict() got set to something else (probably like below), and is no longer the object you think it is.

d = dict()        # new dictionary
print(d)          # it works!

{}    

dict = {}         # dict isn't dict() anymore
d = dict()        # error!

TypeError                                 Traceback (most recent call last)
<ipython-input-12-e3c238d66cd2> in <module>
----> 1 d = dict()

TypeError: 'dict' object is not callable

Answer 2

This error is generated when we try to call a dictionary using invalid methods. As shown in the example below.

Example:

# Creating dictionary 'MyDict'
MyDict= {
'car' : 'Honda city',
'type': 'sedan',
'color' : 'Blue'
}

# Printing Dictionary
print(MyDict())

# Checking length of dictionary
print("length of the dictionary :",len(MyDict))

Output:

File "nterror.py", line 9, in <module>
print(MyDict( ))
TypeError: 'dict' object is not callable
