Lab Description:

This program is based on strings and lists. The first one is a function that takes a string and displays it backwards from the last character to the first. The second one is a function the takes a list and displays the accumulative sum. The second program was more difficult to write than the first.

Code:

Exercise 1, Chapter 8

def backward(x):
    index=-1
    length=(-1*len(x))
    while index >= length:
        letter = x[index]
        print (letter)
        index = index -1
print (backward("dg4346534"))

Exercise 3, Chapter 10

def accum(x):
y=x
index=1
post=0
y[0]=x[0]
y[index]=x[post]+x[index]

while post<index:
index=index+1
post=post+1
if index==len(x):
print (y)
break
y[index]=y[post]+x[index]

t=[1,2,3,4,5,6,7,8]
accum(t)
