python概率計算器實例分析

　　文章主要介紹了python概率計算器實現方法,實例分析了Python實現概率計算的技巧,具有一定參考借鑒價值,需要的朋友可以參考下

　　本文實例講述了python概率計算器實現方法。分享給大家供大家參考。具體實現方法如下：

　　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!

　　希望本文所述對大家的Python程序設計有所幫助。
