I'm using Python 2.6.1 on Mac OS X.
I have two simple Python files (below), but when I run
python update_url.py I get on the terminal:
Traceback (most recent call last): File "update_urls.py", line 7, in <module> main() File "update_urls.py", line 4, in main db = SqliteDBzz() NameError: global name 'SqliteDBzz' is not defined I tried renaming the files and classes differently, which is why there's x and z on the ends. ;)
class SqliteDBzz: connection = '' curser = '' def connect(self): print "foo" def find_or_create(self, table, column, value): print "baar" import sqlitedbx def main(): db = SqliteDBzz() db.connect if __name__ == "__main__": main()

The Python "NameError: name is not defined" occurs when we try to access a variable or function that is not defined or before it is defined. To solve the error, make sure you haven't misspelled the variable's name and access it after it has been declared.
NameError is a kind of error in python that occurs when executing a function, variable, library or string without quotes that have been typed in the code without any previous Declaration. When the interpreter, upon execution, cannot identify the global or a local name, it throws a NameError.
In Python, the NameError occurs when you try to use a variable, function, or module that doesn't exist or wasn't used in a valid way. Some of the common mistakes that cause this error are: Using a variable or function name that is yet to be defined.
You can fix this by doing global new at the start of the function in which you define it. This statement puts it in the global scope, meaning that it is defined at the module level. Therefore, you can access it anywhere in the program and you will not get that error.
You need to do:
import sqlitedbx def main(): db = sqlitedbx.SqliteDBzz() db.connect() if __name__ == "__main__": main() try
from sqlitedbx import SqliteDBzz If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
