Question

sample1.py

class1:
    
    def function(self): 
    
        dbcursor.execute('UPDATE Table')

main.py

from sample1 import class1

inventoryDb = inventory.connect('sample.db')

dbcursor = inventoryDb.cursor()

class = class1()

class.function()

NameError: global name ‘dbcursor’ is not defined

What is causing error here? And, how to fix? Thanks!

Answer 1

dbcursor is only defined in main.py. Why don’t you pass it as a parameter to your function in sample1.py? Something like

def function(self, dbcursor):
    dbcursor.execute('UPDATE Table')

class_ = class1()
inventoryDb = inventory.connect('sample.db')
class_.function(inventoryDb.cursor())
