Hands dirty with Python Numpy arrays

# 't' is [[[1, 1, 1], [2, 2, 2]], [[3, 3, 3], [4, 4, 4]]]
shape(t) ==> [2, 2, 3]

# 't' is [[[1, 1, 1], [2, 2, 2]], [[3, 3, 3], [4, 4, 4]]]]
size(t) ==> 12

# 't' is [[[1, 1, 1], [2, 2, 2]], [[3, 3, 3], [4, 4, 4]]]
# shape of tensor 't' is [2, 2, 3]
rank(t) ==> 3
Note: The rank of a tensor is not the same as the rank of a matrix.

##Big O notations - of algorithms

Big O describes the worst case scenario, can be used to define execution time or space used (e.g. in memory or on disk) by an algorithm.

////////////////////////////////////////////////////////////////////////////////////////////////////////////////
O(1)
executes in same time or space regardless of size of the input data

vals = [None,'jack','and','jill']
