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!
