USING PYTHON PROGRAMMING AND WHILE LOOPS NOT FOR LOOPS

The first step is to copy in the list of

p

rogramming langauges

, and to write code

that will print out the different choices.

Copy the list

below into your programs

main()

:

# types of

p

rogramming languages

to vote on

languages = [

"Python"

,

"Java"

,

"C++"

,

"Ruby"

,

"C"

,

"PHP"

,

"Shakespeare"

]

To print the choices, you should write a while loop

that will print out the

following two things on each line:

The number of the choice (with the count starting at 1, not 0!)

The programming languages name.

This is the second of

four

steps that must be written for this lab.

Now that the

code to display the

p

rogramming languages

i

s complete

, we need

to allow the user and their friends to actually vote!

For now,

we wont worry about storing the votes

. Just write the code that will

allow the user to vote, and will stop when they enter a 0 to quit.

If they make an invalid choice, simply ignore it and ask again

This is the third

of four steps that must be written for this lab.

Now that you can accept votes, we need to store them.

Well store the votes for the programming languages

in another, separate list of integers

.

So if, for example, the user voted for

Python (choice 1),

Shakespeare twice (choice 7)

and

C

++

four times

(choice 3), the vote list would look like this:

votes =

1

0

4

0

0

0

2

index 0

index 1

index 2

index 3

index 4

i

ndex 5

index 6

In other words, the votes

stored

at a give

n index

in

votes

should be

for the

p

rogramming language

stored

at that same index in the

l

anguages

list.

Remember, list indexing starts at 0, but were presenting the choices to the

user starting at 1, so the way you store votes will need to compensate for this

offset. Youll also need to make sure you

i

gnore

invalid input

dont

t

ry to

count a vote for option #

8

, when there are only 7 choices!

At the end, print out the list of votes, so you can ensure your program is

working correctly.

(Simply use

print(

"votes:",

votes)

in your code.)

This is the last of

four

steps that must be written for this lab.

This last step is relatively simple, as

youve already done all of the h

ard work.

For this step, well display the final votes for each

p

rogramming language

. (If

your code that asks for and stores votes doesnt work correctly, you might also

have to do some debugging. Thats how programming works, sometimes!)

Once the user has ent

ered 0 in order to stop voting, you need to go through

the list and print out the number of votes each

p

rogramming language

earned.

You will need to iterate through

both of the lists,in the same while loop,

inNorder to print out the programming lang

uage

and the number of votes it

receiv

ed
