UnboundLocalError: local variable ‘x’ referenced before assignment in Python (HOW TO FIX)


UnboundLocalError: local variable 'x' referenced before assignment

This error occurs when you try to access a local variable before it is assigned a value.

To fix this error, assign a value to the local variable before you try to access it.

What is the UnboundLocalError?

The UnboundLocalError is an error that occurs when you try to access a local variable before it is assigned a value. This error occurs when you try to access a local variable before it is assigned a value.

What is a local variable?

A local variable is a variable that is declared inside a function. It is only accessible within the function and is not accessible outside of the function.

What is an assignment?

An assignment is when you assign a value to a variable. For example, if you have a variable called x and you want to assign it the value 5, you would write x = 5.

Examples of UnboundLocalError

Here is an example of code that will cause an UnboundLocalError:

def my_function():
print(x)
x = 5

my_function()

This code will cause an UnboundLocalError because the variable x is being accessed before it is assigned a value.

How to Fix the UnboundLocalError

To fix this error, assign a value to the local variable before you try to access it. Here is an example of the code above, but with the error fixed:

def my_function():
x = 5
print(x)

my_function()
