NameError: name 'standard_weight' is not defined

This error occurs when you try to use a variable or function that has not been defined in your code. To solve this error, you need to define the variable or function before using it in your code.

For example, if you are trying to use the variable 'standard_weight' in your code, you need to define it first like this:

standard_weight = 70

This will define the variable 'standard_weight' with a value of 70. You can then use this variable in your code without any errors.

NameError: name 'get_default_scheme' is not defined. Did you mean: '_get_default_scheme'?

This error message indicates that the name 'get_default_scheme' is not defined in the current scope. It suggests that perhaps you meant to use the function '_get_default_scheme' instead. You should check your code for any typos or incorrect function names. If you intended to define the 'get_default_scheme' function, make sure it is properly defined before it is called.
