Python probability calculator example analysis

This article illustrates the implementation of python probability calculator. Share with you for your reference. The specific implementation method is as follows:

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!
