[Tutor] IndexError: index out of bounds

[Sayan Chatterjee]

p_za = [None]*N is not giving away the error message.

for i in range(0,N):
    p_za.append = p_initial[i] + t*K*cos(K*p_initial[i]); is also not
working.

Could you please redirect me to a link where the example is demonstrated?
What is the simplest way to assign an array element a value?

i.e the C analogue of:

int array[200]

for(i=0;i<200;i++)
  array[i] = 2*i + 5;
