Question

can someone tell me what i'm doing wrong? on problem set 1, the compound interest one. I finally got everything to work except the round function. I put it inside the loop but it only rounds the result for the first month. I can post my code if it helps.

Answer 1

just realized I can attach files

Answer 2

What version are you using - 3.0 print is a function, so that could create errors. Also, There's a space between float, take it out, That may help.

Answer 3

using 2.7, ill try taking that space out

Answer 4

also, make a function out of it, instead of while, and use the variables as arguments. Call it again using recursion like:

def functionname():
....code;
a+= 1.0;
functionname();
...

Answer 5

okay

Answer 6

but it works exactly like it should until I try to round. shouldn't it loop with everything else?

Answer 7

yeah. I just like functions because they look cleaner and they're easier to work with for me. It's not necessary

Answer 8

sorry im just new to this just trying to figure out what im missing.

Answer 9

I'm not familiar with round and float because I never had to extensively use it. Sorry
You're code looks fine

Answer 10

yea not really an error technically, its just not giving me the result I want. it rounds the value once even though its inside the loop

Answer 11

ok np I appreciate the help

Answer 12

I would do v += 0.00000000000;
I'm gone now.

Answer 13

ok thanks

Answer 14

yeah ok

Answer 15

The `round` function returns the rounded value, it doesn't change the given variable.
you should do `v = round(v,2)`

Answer 16

oh, ok thank you.
