The “UnboundLocalError: local variable referenced before assignment” error occurs in Python when you try to access a local variable before it has been assigned a value. This is typically caused by a typo, or by using the same name for a local variable and a [global variable](http://net-informations.com/python/iq/global.htm) in the same scope or when you forget to assign a value to a local variable before using it.

```auto
    x = x + 1
    print(x) // This code will result in the error

```

to solve this…

```auto
    x = 0 //assign a value to the local variable
    x = x + 1
    print(x)

```

To resolve the “UnboundLocalError: local variable referenced before assignment” error, you need to assign a value to the local variable before you use it. Another way to resolve this error is to use the global keyword to access the global variable with the same name.
