Computer Programming in Python questions?

I saw a similar question, and I am in the same boat. I am an actuarial science major, but I am forced to take the foreign language known as computer science. I actually find it pretty interesting, and I feel like I get it until I get these curve balls.

So, I have 2 questions about how to write 2 programs:

Question 1:

Define the function pascnext(L)

Function pascnext(L) returns a list made from L:

1. L is a list of integers

2. L is supposed to be a row from Pascal's Triangle

3. The result should be a list of integers.

4. The result should be the "next" row in Pascal's Triangle

Hints:

* Look up "Pascal's Triangle" on the web to see the

pattern from one row to the next.

* If L equals [], or L equals [1], then these are

special cases (use an if statement to test for these

cases an return the proper answer); see unit tests

below for expected responses.

>>> pascnext([])

[1]

>>> pascnext([1])

[1, 1]

>>> pascnext([1,1])

[1, 2, 1]

>>> pascnext([1,6,15,20,15,6,1])

[1, 7, 21, 35, 35, 21, 7, 1]

Question 2:

Define a function pascrow(n)

Function pascrow(n) returns a list:

1. n is the "row number" for Pascal's Triangle

2. Row 0 is the top of the triangle, which

is represented as [1].

Requirement:

* Even though there is a mathematical formula

to generate row k of Pascal's triangle, you

MUST use pascnext to compute the answer for

this problem.

Hint:

* in your function, put the line

from pascnext import pascnext

This will allow you to use pascnext(f)

for some f in your definition of pascrow.

>>> pascrow(0)

[1]

>>> pascrow(1)

[1, 1]

>>> pascrow(5)

[1, 5, 10, 10, 5, 1]

>>> pascrow(12)

[1, 12, 66, 220, 495, 792, 924, 792, 495, 220, 66, 12, 1]
