Penguin is a lightweight, customizable stopwatch ⏱ decorator that helps you determine how long it takes for your functions to run. It supports both synchronous (@penguin) and asynchronous (@penguin_async) functions.

To install penguin-py with the command line, run this command:

pip install penguin-py.

To install penguin-py using a requirements.txt file, add this line to your requirements.txt file.

penguin-py==0.3.12

For synchronous functions, use the @penguin() decorator.

✅ To run with default kwargs:

from penguin_py import penguin


@penguin()
def foo(test1, test2=None):
    # Note: this function can be anything!
    for i in range(10000000):
        pass
    return "test", True


test = foo("", test2="")

This will output the following to your logger:

✅ To run with user specified kwargs:

@penguin(
    verbose=True,
    show_args=True,
    show_return=True,
    foreground='cyan',
    background='yellow',
)
def foo(test1, test2=None):
    for i in range(10000000):
        pass
    return "test", True


test = foo("", test2="")

This will output the following to your logger:

Note: For a more detailed list of all kwargs and their defaults, visit this section: List of kwargs

❌ Since penguin is a decorator that takes in kwargs, do not call it without the brackets ().

from penguin_py import penguin


@penguin
def foo(test1, test2=None):
    # Note: this function can be anything!
    for i in range(10000000):
        pass
    return "test", True


test = foo("", test2=":")

If you do this, you'll get a TypeError relating to arguments.

For asynchronous functions, use the @penguin_async() decorator.

✅ To run with default kwargs:

from penguin_py import penguin


@penguin_async()
def foo(test1, test2=None):
    # Note: this function can be anything!
    for i in range(10000000):
        pass
    return "test", True


test = foo("", test2="")

This will output the following to your logger:

✅ To run with user specified kwargs:

@penguin(
    verbose=True,
    show_args=True,
    show_return=True,
    foreground='cyan',
    background='yellow',
)
def foo(test1, test2=None):
    for i in range(10000000):
        pass
    return "test", True


test = foo("", test2="")

This will output the following to your logger:

• verbose: When True, it shows all logs that are described by the other kwargs. When False, each kwarg would determine if that specific log is shown - default: False
• show_args: When True, it shows the function's signature, with the *args and **kwargs being passed in.
  • default: False
• show_return: When True, it shows the function's return value(s).
  • default: False
• foreground: When chosen from this list, ["red", "yellow", "green", "blue", "magenta", "cyan", "grey"], it colour the logger output text the chosen colour.
  • default: "grey"
• background: When chosen from this list, ["red", "yellow", "green", "blue", "magenta", "cyan", "grey", "black", "white"], it colour the logger output background the chosen colour.
  • default: "black"
