This calculator saves the value to be stored in the variable in the Map.

In addition, each statement can be separated by `;`,

and the last statement does not have to be `;`. (similar to `Rust`) 

Supports multi-line calculations and storing result in variables.

### input

```python

a = 13;

a + 2;

1 + 3 * 2 - 3 * 7

```

```python

15

-14

```

### input code

![code](imgs/test_wh.png)

### result

![result](imgs/result.png)

It also guarantees operator precedence.
