This is important, because often in the case of  'concatenation' a real 
concatenation is not needed. But then there is a common tool called 
Matlab, which unlike Python has no concept of lists and make numerical  
programmers think they do. C = [A, B] is a horizontal concatenation in 
Matlab. Too much exposure to Matlab cripples the mind easily.
