python概率计算器实例分析

本文实例讲述了python概率计算器实现方法。分享给大家供大家参考。具体实现方法如下：

    from random import randrange
    #randrange form random module
    def calc_prob(strengths):
      """A function that receives an array of two numbers 
      indicating the strength of each party 
      and returns the winner"""
      if strengths[1]>strengths[0]:
    #Bring the bigger number to the first position in the array
        temp=strengths[0]
        strengths[0]=strengths[1]
        strengths[1]=temp   
      prob1=abs(strengths[0]-strengths[1])
    #The relative strength of the 2 parties
      prob2=randrange(0,100)
    #To calculate the luck that decides the outcome
      if prob2 in range(0,33-prob1):
    #Check if the weaker party is capable of winning. 
    #The condition gets narrower with the increase
    #in relative strengths of each parties
        return strengths[1]
      elif prob2 in range(33-prob1,66-prob1):
      #The middle condition
        return "Draw"
      else:
         return strengths[0]
    #Luck favors the stronger party and if relative strength
    #between the teams is too large, 
    #the match ends up in favor of the stronger party 
    #Example
    calc_prob([50,75]);#Always has to be a list to allow exchange
    #Can be programmed in hundreds of better ways. Good luck!
