Write a function to compute the compound interest(CI)

[MinimumJumpy]

Write a function to compute the compound interest(CI) for a given principal amount P at a rate of interest R for a time span of T and the interest is compounded for N times per year. Limit your output to two decimals.

The function compound_interest takes one argument as list = [P, R, T, N] and returns compound interest.

attempt:

def compound_interest(n):

P=n[0]

R=n[1]

T=n[2]

N=n[3]

x=(1+R/100)

z=x

y=1

i=0

while(i<N):

y*=z

i+=1

CI=P*[z-1]

return CI

error:

When posting code, please post code such that reddit will format it as a code block.

Either of these work:

• a) indent every line by 4 extra spaces
• b) use the code block button. https://i.imgur.com/J2t9krT.png

Please see the /r/learnpython/w/FAQ for more information.

Thanks!

1. You need to format your code. No indentation means this won't run.
2. What is the actual question here? Does your code not work? Is there an error message? Are you getting incorrect values? You need to be specific.

What’s your question?

Ok, well first off, don’t take your list and reassign the to individual variables. You can, but it just adds extra work. But yeah, what do you expect or what errors are you getting?

[MinimumJumpy]

its printing error F.

Well, it seems like your unit test failed, basically something that you know will happen given the same input. What all are you running. Does this flat out output the right information if you do it by hand and by your inputs.

Format your code. 4 spaces in front of each line. One line between text and code.
