Python 3: UnboundLocalError: local variable referenced before ...
UnboundLocalError: local variable 'f' referenced before assignment. Python sees the f is used as a local variable in [f for f in [1, 2, 3]], and decides that it is also a local variable in f(3). You could add a global f statement: def f(x): return x.
How to Fix - UnboundLocalError: Local variable Referenced ...
This error occurs when a local variable is referenced before it has been assigned a value within a function or method. This error typically surfaces when utilizing try-except blocks to handle exceptions, creating a puzzle for developers trying to comprehend its origins and find a solution. Syntax:
UnboundLocalError: local variable ... referenced before ...
1. make sure that the variable is initialized in every code path (in your case: including the else case) 2. initialize the variable to some reasonable default value at the beginning 3. return from the function in the code paths which cannot provide a value for the variable.
UnBoundLocalError: local variable referenced before ...
This is because you try tomodifyservo_quadrant which isn't defined in your function. Python uses global scope by default if you just read a variable. So if you don't modify it everything will work fine. If you need to modify it just add global servo_quadrant at the beginning of your function.
Local variable referenced before assignment in Python
The Python "UnboundLocalError: Local variable referenced before assignment" occurs when we reference a local variable before assigning a value to it in a function. To solve the error, mark the variable as global in the function definition, e.g. global my_var .
UnboundLocalError Local variable Referenced Before Assignment ...
The UnboundLocalError occurs when a local variable is referenced before it has been assigned a value within a function or method.

How to fix UnboundLocalError: local variable 'x' referenced ...
The UnboundLocalError: localvariable 'x' referencedbeforeassignmentoccurs when you reference a variable inside a function before declaring that variable. To resolve this error, you need to use a different variable name when referencing the existing variable, or you can also specify a parameter for the function.
[SOLVED] Local Variable Referenced Before Assignment
This error message is raised when a variable is referenced before it has been assigned a value within the local scope of a function, even though it is a global variable. Here’s an example to help illustrate the problem:
Python UnboundLocalError: local variable referenced before ...
The UnboundLocalError: localvariablereferencedbeforeassignment occurs when you try to reference a local variable before assigning a value to it. Preferably, you can solve this error by passing parameters to your function.
Fixing Python UnboundLocalError: Local Variable 'x' Accessed ...
The UnboundLocalError in Python occurs when a function tries to access a local variable before it has been assigned a value. Variables in Python have scope that defines their level of visibility throughout the code: global scope, local scope, and nonlocal (in nested functions) scope.
