Show the Python statement that creates a list called aList and initializes its values to 7, 3, 5, 2, 8, 6.
Show the Python statement that would output the first 2 values of aList. You must use the slice operator (the colon).
Show the Python statement that would output the last 3 values in aList. You must use the slice operator.

Answer #1
Slicing means using : operator to get the required elements.
Code:
# list for given values
list1 = [7, 3, 5, 2, 8, 6]
# Printing first 2 values in list using slicing
print(list1[:2])
# Printing last 3 values in list using slicing
print(list1[:2:-1])Code screenshot:

In racket, implement a tail-recursive function
called sum-pairs that creates a new list by adding the elements of
an input list in pairs. That is the first element of the resulting
list is the sum of the first two elements of the input, the second
element of the resulting list is the sum of the 3rd and 4th
elements of the input, and so on. If there is an odd number of
elements, then the last element remains unchanged. As...

python 3
For this exercise you are to implement the function poly_iter in
the array-backed list class, which, when called with positive
integer parameters a, b, c, returns an iterator over the values in
the underlying list at indexes a*i2+b*i+c, for i=0, 1,
2, ...
E.g., given an array-backed list lst containing the elements [0,
1, 2, 3, 4, ..., 98, 99], the following code:
for x in lst.poly_iter(2, 3, 4):
print(x)
will produce the output:

(Python 3) If I have a list of keys and 3 lists of values, how
can I append these values into an existing key, value pair in a
dictionary? Say I have:
mykeys = ["John", "Sarah", "Lexi, "Cass"]
values1 = [3, 5, 2, 6]
values2 = [17, 18, 12, 21]
values3 = [4, 7, 3, 0]
How can I make it so my dictionary contains all three values in
each of the keys. i.e.:
{"John" : [3, 17, 4], "Sarah":...

LANGUAGE: SCHEME R5RS
Create a procedure called preceeding that will take a list of
numbers as argument and determine the elements and indices of those
elements that preceed a negative number in the given list. The
returned information should be in the form of a pair of lists:
((values) . (indices)).
E.g.
