Question

the tutorial"s code

Answer 1

You increment x in line 13, and then you print x+1 in line 14.

Therefore you get two print in each iteration of the loop, and the output of X=6 (what is what's bothering you here, from what I understand).

You can change your code to have an additional print after the while loop ends:

x = 0
while x < 5:
    print("Not yet there, X=" + str(x))
    x += 1
print("X=" + str(x))
