Dice rolls stats on Python

Question

I am having some trubles trying to figure out how this function works:

import control

 def sevenStats(numRolls):
     sevenCount=0
     for i in range (numRolls):
         roll = control.rollDie(6) + control.rollDie(6)
         if roll == 7
             sevenCount += 1
      return sevenCount

In particular I didn't catch what this line does:

 roll = control.rollDie(6) + control.rollDie(6)

The purpose of the overall function should be to keep track of a given number's rolls, in this case the number = 7.

Can you help me go trough this? Thank you.

Answer 1

I guess that the function control.rollDie(num) generates a random number between 1 and the indicate number, in this case 6. It roll two dices thats why it add it 2 times. Ans then it counts how many times the sum (roll) is equal to 7.

Answer 2

The function is counting the times you obtain a 7 when throwing two dices in n tries.

roll = control.rollDie(6) + control.rollDie(6)

That line of code sums the values of the two dices you have throw.

Answer 3

control.rollDie(6) generates a random number between 1 and the value given in the parameter which in this case is 6.

roll = control.rollDie(6) + control.rollDie(6)

So what this line does is that it generates two random numbers between 1 and 6 and then adds them together and stores the value in the variable roll
