Examples of complex attributes and method operations in Python

This article mainly introduces Python complex number attributes and method operation operations, and analyzes the operation skills related to Python complex number operations in the form of examples. Code comments are provided with detailed explanations. Friends in need can refer to the examples in this article.

Describes Python complex attribute and method operations. Share it with everyone for your reference, the details are as follows:

复数是由一个实数和一个虚数组合构成，表示为：x+yj
一个负数时一对有序浮点数(x,y)，其中x是实数部分，y是虚数部分。
Python语言中有关负数的概念：
1、虚数不能单独存在，它们总是和一个值为0.0的实数部分一起构成一个复数
2、复数由实数部分和虚数部分构成
3、表示虚数的语法：real+imagej
4、实数部分和虚数部分都是浮点数
5、虚数部分必须有后缀j或J
复数的内建属性：
复数对象拥有数据属性，分别为该复数的实部和虚部。
复数还拥有conjugate方法，调用它可以返回该复数的共轭复数对象。
复数属性：real(复数的实部)、imag(复数的虚部)、conjugate()（返回复数的共轭复数）

class Complex(object):
  '''''创建一个静态属性用来记录类版本号'''
  version=1.0
  '''''创建个复数类，用于操作和初始化复数'''
  def __init__(self,rel=15,img=15j):
    self.realPart=rel
    self.imagPart=img
  #创建复数
  def creatComplex(self):
    return self.realPart+self.imagPart
  #获取输入数字部分的虚部
  def getImg(self):
    #把虚部转换成字符串
    img=str(self.imagPart)
    #对字符串进行切片操作获取数字部分
    img=img[:-1]
    return float(img)
def test():
  print "run test..........."
  com=Complex()
  Cplex= com.creatComplex()
  if Cplex.imag==com.getImg():
    print com.getImg()
  else:
    pass
  if Cplex.real==com.realPart:
    print com.realPart
  else:
    pass
  #原复数
  print "the religion complex is :",Cplex
  #求取共轭复数
  print "the conjugate complex is :",Cplex.conjugate()
