WebJun 18, 2024 · 1 Answer. The assignment a = a + 4 tells the interpreter to use a local version of a instead of the global reference. Now in the assignment a = a + 4, when the interpreter is looking up the value of the local variable a, the interpreter finds the variable to be undefined and will yield UnboundLocalError: local variable 'a' referenced before ...
