If they choose not to roll again (but their most recent roll was not a zero), add

their round score to their total score using

addPoints()

.

G.

Use

getPoints()

to see if the player’s total is greater than or equal to the stored

victory

number.

If

so,

print

out

that

the

player

won

and

call

addWin()

,

then

return;

to end the round. If not, go on to the next player.

Please program to output all integers between 0 and 200 that are divisible by 3 and whose single digit is 6.

2. Give at least three examples that show different features of string slices. Describe the feature illustrated by each example. Invent your own examples.

1. Consider the loop from Section 8.3 of your textbook.

prefixes = 'JKLMNOPQ'

suffix = 'ack'

for letter in prefixes:

   print(letter + suffix)

Put this code into a Python script and run it. Notice that it prints the names "Oack" and "Qack".

Modify the program so that it prints "Ouack" and "Quack" but leaves the other names the same.

Include the modified Python code and the output in your submission.

Write a function named test_sqrt that prints a table like the following using a while loop, where "diff" is the absolute value of the difference between my_sqrt(a) and math.sqrt(a). 

a = 1 | my_sqrt(a) = 1 | math.sqrt(a) = 1.0 | diff = 0.0

a = 2 | my_sqrt(a) = 1.41421356237 | math.sqrt(a) = 1.41421356237 | diff = 2.22044604925e-16

a = 3 | my_sqrt(a) = 1.73205080757 | math.sqrt(a) = 1.73205080757 | diff = 0.0

a = 4 | my_sqrt(a) = 2.0 | math.sqrt(a) = 2.0 | diff = 0.0

a = 5 | my_sqrt(a) = 2.2360679775 | math.sqrt(a) = 2.2360679775 | diff = 0.0

a = 6 | my_sqrt(a) = 2.44948974278 | math.sqrt(a) = 2.44948974278 | diff = 0.0

a = 7 | my_sqrt(a) = 2.64575131106 | math.sqrt(a) = 2.64575131106 | diff = 0.0

a = 8 | my_sqrt(a) = 2.82842712475 | math.sqrt(a) = 2.82842712475 | diff = 4.4408920985e-16

a = 9 | my_sqrt(a) = 3.0 | math.sqrt(a) = 3.0 | diff = 0.0 

Modify your program so that it outputs lines for a values from 1 to 25 instead of just 1 to 9.

Encapsulate the following Python code from Section 7.5 in a function named my_sqrt that takes a as a parameter, chooses a starting value for x, and returns an estimate of the square root of a. 

while True:

   y = (x + a/x) / 2.0

   if y == x:

     break

   x = y 

 Each of the following Python functions is supposed to check whether its argument has any lowercase letters.

For each function, describe what it actually does when called with a string argument. If it does not correctly check for lowercase letters, give an example argument that produces incorrect results, and describe why the result is incorrect.

# 1

def any_lowercase1(s):

   for c in s:

     if c.islower():

        return True

     else:

        return False

# 2

def any_lowercase2(s):

   for c in s:

     if 'c'.islower():

        return 'True'

     else:

        return 'False'

# 3

def any_lowercase3(s):

   for c in s:

     flag = c.islower()

   return flag

# 4

def any_lowercase4(s):

   flag = False

   for c in s:

     flag = flag or c.islower()

   return flag

# 5

def any_lowercase5(s):

   for c in s:

     if not c.islower():

        return False

   return True
