4 Respostasguys this code I wrote passed all the unittest specifications in an oop lab. but they told me that I failed a hidden test. that my code can still be improved upon. I've tried my best but I don't know how to improve the code again. please give me ideas. am I using WET in any block. any unnecessary repetitions or redundancy? this is the code below:

so although using srand(time(0)) can be used to get truly random numbers, how truly random are they? For example, if one were to call this method at the same time (in this example, if one were to use this command at 51s) each time would the numbers generated be the same???
If so, are the numbers still truly random??
And if this theory is true, how can one generate truly random numbers that cannot repeat based on external variables (e.g., time)?

4 Respostasx = 42;
int num = 0;
while (num <3)
Consele.writeline (x);
num++;
int x = 42; is just an int with an asigned value of 42
int num=0; is what initiate the count for the while loop
while (num < 3); means 0<3 true, 1< 3 true, 2<3 true, the loop end at 2 bc 3 <3 is false
consele.writeline (x) will display 42 while num < 3
num++ will execute and then add 1 to check if the while loop still true, but it stop at 2, bc 3 makes it false.
so the consele.write will write 42 three times. x=42, remember the (x)

2 RespostasHey there,
I don't know why, but when I import tkinter on IDLE like this:
from tkinter import *
And I say:
window = Tk()
Even known I use python 3.2.5, which should be able to use Tkinter, the python shell raises a ValueError that says that Tk() is not defined. I am very sure I use python 3.2.5 and tutorials from the Python Foundation say that is what I have to do. But it still doesn't work.
Does anyone have an idea of how to solve this problem? Thank you!
