How can I avoid NameError in Python?
To avoid NameError in Python, ensure that all variables are defined before you use them.
What causes a NameError in the first place?
A NameError occurs when you try to use a variable that hasn't been defined or is out of scope.
Can you give me an example of a NameError?
Sure! For instance, if you try to print a variable x without defining it first, you'll get a NameError.
How can I check if a variable is defined?
You can use the locals() or globals() functions to check if a variable is defined in the current scope.
