Python Question

Here's the equation

`x + x^2/2 + x^3/3 +.... x^n/n`

How will I find the sum of this series? x is a constant term to be entered by user and n which is power is also based on user!

I made this program but it's not working properly.. Have a look -

`n=input("Enter power ")`

x=input("Enter value of x")

i=0

while i<n:

c=n-1

res=(x**(n-c))/(n-(c))

print res

i=i+1

So how do we make it? Thanks a ton for your help!

Answer

Something like this for your loop? Tried to keep it simple.

```
n = input("Enter power ")
x = float(input("Enter value of x"))
ans = 0
for i in range(1, n+1):
ans += x**i/i
print(ans)
```
