Why Am I Getting 'NameError: Name 'k' is Not Defined' in Python?

NameError: Name 'Variable Name' is Not Defined in Python

This error typically occurs when Python cannot find a variable with a given name in the current scope. In your case, you are encountering the error "NameError: name 'k' is not defined" after receiving user input.

To resolve this issue, you should ensure that the variable being used has been correctly defined in your code. In Python 2.x, input() is used for user interaction, while raw_input() is deprecated. Therefore, replace the following line:

UserName = input("Please enter your name: ")

With this line:

UserName = raw_input("Please enter your name: ")

Additionally, ensure that the variable UserName is defined within the appropriate scope and that it is spelled correctly.
