Unable to print stuff from while loop

[Nick1507]

Alright so hello everyone, I'm a noob and have really little experience in Python so pls go easy on me. My question in this post is why I'm unable to print(mytab[i]) in this code.

1 2 3 4 5 6 7 8 9 10 11 12 13 14

i=0   mytab = list(range(1,5)) while True:       mytab[i]+=mytab[i]     print(mytab[i])     i+=1         if i>3:         break       print(mytab[i])

It is just a simple one I think so but i can't detect the problem in this code. So pls can you guys help me in fixing this problem and see what is the issue that i am facing.

Line 13 : print(mytab[i])
If the value of i exceeds 3, you "break".
index [4] is not assigned a value.

Because it is outside the index element. scan by loop:

1 2 3 4 5 6 7 8 9

i=0 mytab = list(range(1,5)) while True:     mytab[i]+=mytab[i]     i+=1      if i>3:         break for item in mytab:         print(item)
