Python-printr documentation

printr is a module that allows to emulate the print_r() function of PHP by printing the objects properties of a class instance and its internal structure.

Using printr module for Python

First, you must get an object of a class instance and then, you can call to the printr function by passing the object like an argument function.

Example:

# -*- coding: utf-8 -*-


class Vidrio(object):

    def __init__(self):
        self.color = ''
        
        
class Marco(object):

    def __init__(self):
        self.color = ''
        self.material = ''
        self.vidrio = Vidrio()


class Ventana(object):
    
    def __init__(self):
        self.posicion = ''
        self.marco = Marco()


from printr import printr
ventana = Ventana()
printr(ventana)


Returns:

<Ventana object>
    {
        posicion: ''
        marco: <Marco object>
        {
            color: ''
            vidrio: <Vidrio object>
            {
                color: ''
            }
            material: ''
        }
    }

Advanced use of Python-printr

You can set the character using for identation. By default is white space. Change this value by modifying the IDENTATION_CHAR constant:

import printr
printr.IDENTATION_CHAR = "."  # use point to identation
myobject = MyClass()
printr.printr(myobject)

Also, you can set the identation width, by modifying the TAB_WIDTH constant (by default is 4):

import printr
printr.TAB_WIDTH = 2
myobject = MyClass()
printr.printr(myobject)
