#### Creating a Calculator Class in Python

This technical problem explains how to create a calculator class in Python that can perform addition, subtraction, multiplication, and division operations. The calculator takes two operands (numbers) and an operator as input, and returns the result of the operation.

#### Problem

```Implement a basic calculator class that can perform addition, subtraction, multiplication, and division operations. The calculator should take two operands (numbers) and an operator as input, and return the result of the operation.
Example input:
calculator = Calculator()
result = calculator.calculate(10, "+", 5)
print(result)
Example output:
15```

```class Calculator:
def __init__(self):
pass

def calculate(self, num1, operator, num2):
if operator == "+":
return num1 + num2
elif operator == "-":
return num1 - num2
elif operator == "*":
return num1 * num2
elif operator == "/":
return num1 / num2
else:
return "Invalid operator"

calculator = Calculator()
result = calculator.calculate(10, "+", 5)
print(result)

The solution is optimal because it is simple and easy to understand. It is also easy to add more operators if needed.
