GPT-4 User Generalize this code into one function that takes an operator: ``` def add(x,y): return x + y def sub(x,y): return x - y ``` ChatGPT To generalize the provided code, you might create a function that takes three arguments: two numbers and an operator (in the form of a string, for example), and then performs the corresponding operation. Here's an example: ```python def operate(x, y, operator): if operator == 'add': return x + y elif operator == 'sub': return x - y else: raise ValueError("Operator not recognized. Use 'add' or 'sub'.") ``` Usage: ```python result = operate(5, 3, 'add') # 8 result = operate(5, 3, 'sub') # 2 ``` However, to make it even more scalable and Pythonic, you might use the operator module which contains function equivalents for the infix operators: ```python import operator def operate(x, y, op): ops = { 'add': operator.add, 'sub': operator.sub } if op not in ops: raise ValueError("Operator not recognized. Use 'add' or 'sub'.") return ops[op](x, y) ``` Usage: ```python result = operate(5, 3, 'add') # 8 result = operate(5, 3, 'sub') # 2 ``` This makes it very easy to expand your function to handle additional operations. Just add more operators to the `ops` dictionary, mapping strings to functions from the operator module: ```python ops = { 'add': operator.add, 'sub': operator.sub, 'mul': operator.mul, 'div': operator.truediv } ``` Now your `operate` function can handle addition, subtraction, multiplication, and division with the appropriate string argument.
