Basic Indexing

[rsokl]

Basic Indexing needs proofreading, and code-blocks need verification for correctness.

Few comments (again, no line numbers because diffs on json are gross):

• "Indexing into and slicing along the dimensions of an array is known as -> "are known as"

• "provided a comprehensive rundown the use of" -> "rundown on the use of"

• "Using a Tuple as a N-dimensional Index" -> "as an N-dimensional index"

• "every time we index into a an array" -> get rid of the extra 'a'

• I.e. x[i, j, k] is equivalent" -> That is, x[i, j, k] is" because capitalized I is weird and an abbreviation at the beginning of a sentence is odd.

• "Given a N-dimensional array, x" -> an N-dimensional

Reading comprehension: Ellipsis

I don't know what this question is asking. You "axis entry-0 of axis-0, the last entry of axis-$N-1$, slicing along all intermediate dimensions" but I have no idea what that means. I assume that's access entry-0, but I'm not sure where the last entry comes in.

• "which of the following indexing schemes perform basic indexing." -> make it a question

• There are two hanging Jupyter code cells that I assume were for scratch. Delete those.

• "creates a distinct array, and assigns the variable subarray to that new array." -> assigns that new array to the variable subarray.

• "Which of the following create views x? That is" -> "create views of x"

• "versus performing operations that produces an array" -> produce an array

• "Assigning a to a new array simply changes..." -> "Assigning a new array to a simply changes"

• "Assign row-0, colum-0 with the value" -> "Assign row-0, column-0 the value" (get rid of 'with')

• Same for row-0, column-2 below that

• "Recall from our discussion of basic mathematic expressions in Python" -> "mathematical expressions"

• I.e. the assignment expression x = x + 5 -> For example, the assignment...

• "arrays update the underyling data reference by that" -> "arrays update the underlying data referenced by that" (spell underlying correctly and change reference to referenced)

• "Benefits and Risks to Autgmenting Data" -> Benefits and Risks of

• "This will affect any arras that are views" -> arrays that are views

@davidmascharka this is the entire review, right?

[davidmascharka]

Yep, everything else looked good to me.

These were awesome. Super easy to find/replace all the fixes!
