Python NameError: global name ‘—‘ is not defined

Posted On April 30, 2023

This error occurs when Python cannot find a variable or function that you are trying to use in your code. The “—” in the error message would be the name of the variable or function that Python cannot find.

There are a few common reasons why you might see this error message:

1. The variable or function was not defined: If you are trying to use a variable or function that has not been defined in your code, Python will raise a NameError. Make sure that you have defined the variable or function before using it.
2. The variable or function is out of scope: Variables and functions can only be accessed from within the scope in which they were defined. If you are trying to access a variable or function from outside of its scope, you will see a NameError. Make sure that the variable or function is defined in the correct scope.
3. The variable or function has been misspelled: Python is case-sensitive, so if you misspell the name of a variable or function, Python will not be able to find it. Check that you have spelled the name correctly and that it matches the name of the variable or function as it was defined.

To fix this error, you should check that the variable or function is defined and spelled correctly, and that it is in scope where it is being used.
