Another alternative to ldesnogu approach is to use an AI to convert the code.
This gives this which seem to work. At least it runs without an error.

Code:


import time

# Initialize variables
t0 = time.time()
Y = 30000
List1 = [0] * (Y + 1)
L = 0

# Loop from 1 to 999999
for N in range(1, 1000000):
    M = N
    C = 0
    while M != 1:
        if M % 2 == 0:
            M = M // 2
        else:
            M = 3 * M + 1
        C += 1
        if M <= Y:
            if List1[M] != 0:
                C += List1[M]
                M = 1
    if N <= Y:
        if List1[N] == 0:
            List1[N] = C
    if C > L:
        L = C
        print(N)
        print(C)

print(f"{time.time() - t0} seconds")
