Project description

pituo

Go-styled errors in Python.

Installation

Using pip: pip install -U pituo

Usage

Import the function pituo from the package:

from pituo import pituo

Using decorator syntax

@pituo
def divide(dividend, divisor):
    """
    Return the result of the division between dividend and divisor.
    May raise a ZeroDivisionError if divisor is 0.
    """
    return dividend / divisor

quotient, err = divide(1, 0)

if err is not None:
    print(err)          # Prints "division by zero"
else:
    print(quotient)

Wrapping the function

def divide(dividend, divisor):
    """
    Return the result of the division between dividend and divisor.
    May raise a ZeroDivisionError if divisor is 0.
    """
    return dividend / divisor

divide = pituo(divide)

quotient, err = divide(4, 1)

if err is not None:
    print(err)
else:
    print(quotient)     # Prints 4
