What is an UnboundLocalError in Python?

Can you explain what an UnboundLocalError is in Python?

An UnboundLocalError occurs when a local variable is referenced before it has been assigned a value.

Can you give me an example of when this error might happen?

Sure! If you try to use a variable inside a function without assigning it first, you'll get this error.

Can you show me a code snippet that demonstrates this?

Absolutely! Here's an example:

def my_function():
    print(x)  # Trying to print x before it's defined
    x = 10

my_function()

This will raise an UnboundLocalError.

How can I fix this error in my code?

You can fix it by ensuring that the variable is assigned a value before you try to use it, like this:

def my_function():
    x = 10
    print(x)

my_function()
