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 the 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 wrappers

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

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

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

I would like to log function calls and their results in a clean and organized way. How can I modify the log_function_call decorator to achieve this? Also, what is the best procedure to setup the logger in Python to capture these logs effectively? Any code examples or recommendations would be greatly appreciated. Thank you!
