Decorators for Developers

wrapworks

Introduction

The wrapworks package provides decorators and helper functions for various functionalities such as timing function execution, handling exceptions, and automatic function retries.

Installation

You can install wrapworks using pip:

pip install wrapworks

Features

• timeit: Decorator to print the execution duration of a function.
• tryexcept: Decorator to add a try-except block around a function.
• retry: Decorator to automatically retry a function.

Usage

Timing Function Execution

from wrapworks import timeit

@timeit()
def my_function():
    pass

Handling Exceptions

from wrapworks import tryexcept

@tryexcept(default_return=None)
def another_function():
    pass

Automatic Function Retries

from wrapworks import retry

@retry(max_retries=3, delay=1, default_return=None)
def some_function():
    pass

Easy printing of exceptions

from wrapworks import eprint

def some_function():
    try:
        raise ValueError()
    except Exception as e:
        eprint(e , some_function)

Add current directory to system path and load environment variables

from wrapworks import cwdtoenv
cwdtoenv()

Customizing Output

You can customize the output behavior of the wrapworks decorators by specifying a level parameter when using them.

Additionally, you can further control the display of print statements based on the WRAPWORKSLEVEL environment variable as follows:

• If the level parameter in a decorator is higher than the WRAPWORKSLEVEL environment variable, the print statement from that decorator will be displayed.
• Set WRAPWORKSLEVEL to a specific level (e.g., 1, 2, 3, etc.) to control which decorators' print statements are shown based on their respective levels.
• Print statements from decorators with a level lower than the WRAPWORKSLEVEL will be suppressed, providing a cleaner output in the console or log files.
