ez-life 1.0.2

A Python Package to make life ez for pythonistas

ez_life

The objective of ez_life is to make coding with Python easier by removing repetitive code while still maintaining the same level of functionality

Installation

pip install -U ez_life

param2attr

• Here is a little sneak peak of what you can do with this package!
  • First consider this code block:

from ez_life import Param2attr

class Foo:
	def __init__(self, param1 = None, param2 = None, param3 = None):
		# This sux
			self.param1 = param1
			self.param2 = param2
			self.param3 = param3

• We can instead create a class that looks like this, using a property decorator to perform the param to attribute assignments

class Foo:
	@Param2attr(exclude=None) 
	def __init__(self, param1 = None, param2 = None, param3 = None): 
		# this good, allows u to write other code here during initialization 
		pass

• If you are interested to learn about the implementation or other features that param2attr supports, feel free to read the documentation

JTProperty

• Ez_life can also manage variable dependencies, building upon the @property decorator!

• First here's some code with the classic @property decorator:

class SetAndGet:
  def __init__(self, r = 1):
    # initialise the protected variable
    self._radius = None

    # calls the @radius.setter method
    self.radius = r
  @property
  def radius(self):
    if self._radius is None:
      self.radius = 2
    return self._radius
  @radius.setter
  def radius(self, r):
    if r <= 0:
      raise ValueError("radius should be greater than 0")
    self._radius = r

• Using the @JTProperty decorator, we can see that we can abstract away the self._radius variable and hence write less code!

from ez_life import JTProperty

class JTSetAndGet:
  def __init__(self, r = 1):
    self.radius = r
  @JTProperty(setter = True)
  def radius(self):
    return 2

  @radius.setter
  def radius(self, r):
    if r <= 0:
      raise ValueError("radius should be greater than 0")
    return r

• JTProperty also supports a variety of other features including:
  • Automatic setter creation
  • Graph Dependencies
    • Support for inheritence
• Read the documentation here to learn about these features!
