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.
