NameError: name ‘x’ is not defined python

NameError: name ‘x’ is not defined is a common error in Python that occurs when a variable or function is referenced before it has been defined.

Reason of error:

The error occurs when the interpreter cannot find a reference to a name (variable or function) in the local or global scope. This can happen if the name is misspelled or if the reference is made before the name has been defined.

Example code:

The following code snippet will raise a NameError: name ‘x’ is not defined:


Solution to solve issue:

To fix the error, ensure that the name has been defined before it is referenced. Check for spelling errors or typos in the name. If the name is defined in another module, make sure to import the module and use the correct namespace. If the error persists, use the built-in globals() and locals() functions to inspect the current scope and see if the name is defined.

x = 'onlevelup'
