Scope Traps for Python

Problem finding: The "local" variable inside the For loop, after an exception, the assigned variable still has a value to output.

Each loop is output and no duplicates are found.

Conclusion: There is no "local" variable in for.

The variable scope within Python, the minimum is in the function unit.

Above is the class, and then the module.

For this problem, and the output is not duplicated, because an exception occurred after the assignment statement block, the output of the design is not good.

The value that is actually output is the value that was assigned in the last loop.
