unboundlocalerror local variable 'x0' referenced before assignment

This is because, even though Var1 exists, you're also using an assignment statement on the name Var1 inside of the function (Var1 -= 1 at the bottom line). Naturally, this creates a variable inside the function's scope called Var1 (truthfully, a -= or += will only update (reassign) an existing variable, but for reasons unknown (likely consistency in this context), Python treats it as an ...

How to solve the "local variable 'stressed' referenced before assignment" error? 1 Weird behavior - UnboundLocalError: local variable 'n' referenced before assignment

运行会出错：UnboundLocalError: local variable 'x' referenced before assignment。 这是因为对于fun1函数，x是局部变量，对于fun2函数，x是非全局的外部变量。 当在fun2中对x进行修改时，会将x视为fun2的局部变量，屏蔽掉fun1中对x的定义；如果仅仅在fun2中对x进行读取，则不会 ...

UnboundLocalError: local variable 'tests' referenced before assignment I've tried many different things to try to get tests to go to get_initial_input() but it says that it is referenced before assignment. How is that possible when the first line of code I'm trying to define it?

Returns: UnboundLocalError: local variable 'take_sum' referenced before assignment. Question 1: How is take_sum referenced before assignment if it exists in the global scope and the if-statement in main evalutes to False? So let's add an else clause to the if-statement:

UnboundLocalError: local variable 'player1_head' referenced before assignment from turtle import * from random import randint from utils import square, vector player1_xy = vector(-100, 0) player1_aim = vector(4, 0) player1_body = [] player1_head = "It looks like I'm assigning here."

The traceback page shows that the POST did pass some variable. Help me please, I cant figure it out why it works on Supplier, but not Item. P/S: Sorry for the indentation.

Same as "return np.array((x1,y1,x2,y2))", if the variables are None then pass, I have tried if x1 or y1 or x2 or y2 is not None then return but it didn't work so I used try except but it still didn't work.

It is because for copy_matrix there is no local variable there, so it references the nonlocal variable present at line 6 ie copy_matrix = {}, while for cur_max it is being defined as a local variable in line 24 ie cur_max = max(cur_max, copy_matrix[(r, c)]), it is referencing nonlocal variables for copy_matirx, rows, columns but it is ...

I'd set p, q, and r to -1, then run the if statements to set one of them to 0, as all three of those variables run the risk of being undefined in the for loop. - MasterOdin Commented Apr 26, 2015 at 17:30
