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


#coding=utf8
'''''
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()
if __name__=="__main__":
  test()

PHP and Python: Code Examples and Comparison PHP and Python: Code Examples and Comparison Apr 15, 2025 am 12:07 AM

PHP and Python have their own advantages and disadvantages, and the choice depends on project needs and personal preferences. 1.PHP is suitable for rapid development and maintenance of large-scale web applications. 2. Python dominates the field of data science and machine learning.

Python vs. JavaScript: Community, Libraries, and Resources Python vs. JavaScript: Community, Libraries, and Resources Apr 15, 2025 am 12:16 AM

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

How is the GPU support for PyTorch on CentOS How is the GPU support for PyTorch on CentOS Apr 14, 2025 pm 06:48 PM

Enable PyTorch GPU acceleration on CentOS system requires the installation of CUDA, cuDNN and GPU versions of PyTorch. The following steps will guide you through the process: CUDA and cuDNN installation determine CUDA version compatibility: Use the nvidia-smi command to view the CUDA version supported by your NVIDIA graphics card. For example, your MX450 graphics card may support CUDA11.1 or higher. Download and install CUDAToolkit: Visit the official website of NVIDIACUDAToolkit and download and install the corresponding version according to the highest CUDA version supported by your graphics card. Install cuDNN library:

Detailed explanation of docker principle Detailed explanation of docker principle Apr 14, 2025 pm 11:57 PM

Docker uses Linux kernel features to provide an efficient and isolated application running environment. Its working principle is as follows: 1. The mirror is used as a read-only template, which contains everything you need to run the application; 2. The Union File System (UnionFS) stacks multiple file systems, only storing the differences, saving space and speeding up; 3. The daemon manages the mirrors and containers, and the client uses them for interaction; 4. Namespaces and cgroups implement container isolation and resource limitations; 5. Multiple network modes support container interconnection. Only by understanding these core concepts can you better utilize Docker.
