## Python Basic: Exercise-39 with Solution

Write a Python program to compute the future value of a specified principal amount, rate of interest, and a number of years.

The formula for future value with compound interest is FV = P(1 + r/n)^nt.
FV = the future value;
P = the principal;
r = the annual interest rate expressed as a decimal;
n = the number of times interest is paid each year;
t = time in years.

Test Data : amt = 10000, int = 3.5, years = 7
Expected Output : 12722.79

Sample Solution:

Python Code:

``````amt = 10000
int = 3.5
years = 7
future_value = amt*((1+(0.01*int)) ** years)
print(round(future_value,2))
```
```

Sample Output:

```12722.79

## Python: Tips of the Day

Unpack variables from iterable:

```# One can unpack all iterables (tuples, list etc)
>>> a, b, c = 1, 2, 3
>>> a, b, c
(1, 2, 3)

>>> a, b, c = [1, 2, 3]
>>> a, b, c
(1, 2, 3)
```
