Basic Calculator

Implement a class Calculator with a private attribute for the current value. Include methods for basic operations while ensuring that certain erroneous operations (e.g., division by zero) are handled appropriately.

Example 1:

Input: 10, "+", 5
Output: 15

Example 2:

Input: 5, "/", 0
Output: "Division by zero error"

You can use exception handling to catch and handle division by zero errors.


class Calculator:
def __init__(self, initial_value=0):
self._current_value = initial_value

def add(self, value):
self._current_value += value

def subtract(self, value):
self._current_value -= value

def multiply(self, value):
self._current_value *= value

def divide(self, value):
self._current_value /= value
except ZeroDivisionError:
return “Division by zero error”

def get_current_value(self):
return self._current_value

# Test the class
calculator = Calculator(10)
print(calculator.get_current_value()) # Output: 15
calculator.divide(0) # Output: Division by zero error
