Index Error Issue

Question

I ran into an Index Error issue in my code and I can’t find the reason behind it. This is the code:

It should look like the following code, but including the index for each y value:

Any suggestions?

Answer 1

When the value of "i" is 5 your "primes" list looks like this:
[1, 5, 7]

So accesing primes[5] gives you an IndexError since there are only 3 elements.

Remove line 11 and everything should work properly:
print("i: "+ str(i) + " --> " + "result: " + str(primes[i]))

Answer 2

Try this:

from math import sqrt
primes = []
def prime_gen(x):
index = 0
i = 0
while index < x:
y = sqrt(24*i+1)
int_y = int(y)
if y == int_y :
primes.append(int_y)
print(f"i: {i} -> result: {primes[index]}")
index += 1
i += 1

prime_gen(10)
