While compiling, Python sees the assignment to X and decides that X will be a local name everywhere in the function. Other names are defined within the program (such as variables). This means that you cannot declare a variable after you try to use it in your code.

My function works fine without adding the try/except/else blocks. The code fails with. Name 'x' is not defined.

The first video in the series dedicated to debugging various python errors. I am a complete beginner in python. Some of my friends inspired me to learn computer programming and suggested me the python language.

The error means that Python looks for something named x but finds nothing defined by that name. A NameError is raised when you try to use a variable or a function name that is not valid. However, after I added the block;.

Python knows the purposes of certain names (such as names of built-in functions like print). If Python encounters a name that it doesn't recognize, you'll probably get this error. It's simply not defined nowhere in the code.

But later, when the function is actually run, the assignment hasn’t yet happened when the print executes, so Python says you’re using an undefined name. The x in the error will vary depending on your program. In Python, code runs from top to bottom.

This video covers the NameError within python. Pass Or it wasn't imported:. Name 'add' is not defined.
