Which error will be thrown when a variable is deleted using del
In Python, a NameError occurs when an identifier (variable, function, class, etc.) is undefined. This error occurs when Python encounters a variable or an identifier that it doesn't recognize or cannot find in the current namespace.
NameError can occur due to various reasons. One common reason for a NameError is when a variable is referenced before it is defined. Another reason for the occurrence of NameError is when the name is misspelled or mistakenly written in the wrong case.
Sometimes, it can also occur when you try to access a variable outside of its scope. When this error occurs, Python interpreter raises an exception with a message stating the name that caused the error.
As a programmer, it's essential to handle such errors in Python by using try and except statements and also verifying that all variables are correctly defined and accessed within their intended scope.
