What is Part in Mathematica?
Part is a structural function that gives a specified indexed part of an expression. The expression Part[expr,i] is commonly represented using the shorthand syntax expr[[i]] or expr〚i〛. Part can be used to pick out parts of lists, a sequence of parts, elements of matrices, rows and columns of matrices, and so forth.
