Overview

This package is created to make the debug process much easier for python projects.

Algorithm

This package imports @debug decorator for functions and methods, which:

1. Prints all arguments taken by function and their types.
2. Show how long is instance running in seconds.
3. Catches and prints out detailed information about all exceptions.
4. Prints out all returned values and their types.

Usage

1. Import debug from clevdebug library: from clevdebug import debug
2. Add @debug decorator to the function or method: @debug
3. Run the script.

Examples

There are several usage cases.

Simple Example

# import debug from clevdebug
from clevdebug import debug


# Debugger for function
@debug
def foob(a, b):
    return b


# Debugger for method in class
class Boof:
    @debug
    def __init__(a, b) -> None:
        pass


if __name__ == '__main__':
    boo = Boof(1, b = 2)
    foob(1, 2)

Output is:

Catching errors

# import debug from clevdebug
from clevdebug import debug


# Debugger for function
@debug
def foob(a, b):
    return b/0


if __name__ == '__main__':
    foob(1, 2)

Output is:

Do not use to class

from clevdebug import debug


@debug
class A:
    def __init__(self, a, b):
        self.a = a
        self.b = b


if __name__ == '__main__':
    A(1, 2)

Output is:

TypeError: Only functions or methods INSIDE a class can be debugged

Installation

pip install clevdebug
