Python Decorators: Custom Logging for Function Calls


I'm working on a Python project where I have multiple functions, and I want to log each function call along with its arguments and return value for debugging purposes. I've heard that decorators can help achieve this. Could someone guide me on how to create a custom decorator for logging function calls?

Here's what I have in mind:


def log_function_call(func):
def wrapper(*args, **kwargs):
# Log function call, arguments, and return value
result = func(*args, **kwargs)
# Log the result
return result
return wrapper

def add(a, b):
return a + b

def subtract(a, b):
return a - b

# Example function calls
result1 = add(5, 3)
result2 = subtract(10, 4)


I'd like to log the function calls and their results in a clean and organized manner. How can I modify the log_function_call decorator to achieve this? Additionally, what's the best practice for configuring the logger in Python to capture these logs effectively? Any code examples or recommendations would be greatly appreciated. Thank you!
