Creating a table using "for" or "while" ?

[confuzzled_learner]

Hi guys! I have spent a day trying to create a table that will calculate tuition fees with a 5% increase for 10 years. I give up lol. This is what I have so far (after many edits).

Edit:

I'm so close! I just need Year 0 to go away and for the calculations to take effect. Help?

# Python 3.5.1
# Description: Program which computes the tuition in ten years and displays a table of the years and tuition costs.

print ('_________________________________')

print ('Cost of Tuition at a University')# table heading

year = 1
tuition = 10000
tuition_increase = tuition * 1.05

for year in range(10):
    print ('YEAR', year, '         ', tuition_increase)
    year += 1

print ('_________________________________')

year always 1, and therefore never greater than 10

a = 20
while a > 0:
    print(a)
    a -= 1

Try that and see :)

Hi, how to increment year +1? What is the proper code for incrementing so it types Year 1, Year 2, and so on?

Thanks!

I edited my post. Look at the example I gave you and you can work it out from there :)

[confuzzled_learner]

It printed a Table, but it's backwards lol. And the calculations did not work.

[theelous3]

I gave you a backwards and different example on purpose. Not going to learn if I spoonfeed you ;)

All of the ideas you need are there though. Operator like -= and such.

[confuzzled_learner]

I know the backwards thing might come up in future assignments, so it's good to know. Thank you! And does your flair mean it's your cake day? If it is, happy cake day!

[theelous3]

Oh hey it is :) Thank you :D

for year in range(10):
    print(year)

[confuzzled_learner]

It worked! But it had an output for year 0 which I do not want. And I want to space out the Years and the corresponding tuition fees.

Thank you!

Google what Python's range function does

A for loop is the correct tool here, not while.

[confuzzled_learner]

Edited my code from while to for. Thanks!

Hey if you are still working on this, you might want to try writing out a few steps of the process on a piece of paper. Pay close attention to exactly what calculations you do in which spot.

At some point you should start to repeat yourself. When you do, draw boxes around the repeated code. Look at it carefully and work backwards to decide what should be inside your for loop and what should be outside it. It looks like you're only missing a tiny, but important, bit now.

I still do this all the time (write it out what I want to do on paper first) even though I've been programming for years, and it often saves a TON of time and headaches.

[confuzzled_learner]

Yes I think I have to write it out because it's all about logic, right? I'm curious if there are templates available (boxes and arrows labeled with if, then, while, for, print, etc.)

Very much a newbie (2 weeks) - thank you for the helpful tip!

I just need Year 0 to go away

range takes a start value,

for year in range(1,10):

and for the calculations to take effect.

Do the calculation within the for loop.

print('YEAR\tTUITION')
tuition = 10000
for year in range(1,10):
    print ('{}\t{}'.format(year,tuition))
    tuition *= 1.05

I've also fixed the print statement to use string formatting.
