From the docs: str.split([sep[, maxsplit]])Return a list of the words in the string, using sep as the delimiter string. 3. Create a counters array for each element you want to split at then write a condition in this fashion: So basically you are finding the start and end index of the matching pattern within the list. First of all, youre going to need to find the unique integer divisors of the given number of chunks: Every number is divisible by one and itself, so you add those to the resulting set of divisors. Heres how you can fill such a chunk with random values and then read one of the pixels back: Note that the top-left pixel located in the first row and the first column has absolute coordinates equal to 960 and 540.
