# Calculator
A simple calculator class library written in python just for fun!
## How to
Just clone the repo, head to the directory and `(py main.py)`
You can also add your custom operators for the calculator (`See calculator/operators/custome_operator` to see current examples)
This project can easlly extends as you wish (This is just the simple and base version)
### Example
After you copied Calculator folder into your project, Just create a file like `main.py`, copy-paste code below for quick start:
```python
from calculator import Calculator
from random import choice
if __name__ == "__main__":
# Show time
c = Calculator()
print(c.direct_calculate("2*(10+5)"))
```
**A prettier use is shown in `main.py`, of repo directory.**
Here is a example of a custom operator that takes two number and returns a random number between them
```python
class RandOpertator(GroupingOperator):
def __init__(self, members = []) -> None:
self.pointers = ['rand(']
self.members = members
self.require_member = 2
super().__init__()
def add_members(self, members):
return super().add_members(members=members)
def calculate(self):
if self.check_members():
import random
return random.randint(self.members[0], self.members[1])
def set_members(self, index, text:list):
end_index = text.index(')', index)
members = ''.join(text[index + 1:end_index]).split(',')
self.add_members([int(members[0]), int(members[1])])
return index, end_index
```
Please take a look in Operator abstract class and other operators to find out whats happend!
