A beginner question for Modulo with exponentiation calculation

Question

The question is below but how is it calculated in Py and what command should I be entering in Py? Suppose you have $100, which you can invest with a 10% return each year. After one year, it's 100×1.1=110 dollars, and after two years it's 100×1.1×1.1=121. how much money you end up with after 7 years.

Please help.

Thanks to all who answer.

Sorry, what does this have to do with modulo? Your question is very unclear... — juanpa.arrivillaga, Aug 31 '18 at 02:45
Hello John, is your question `how to compute 100 x 1.1^7 with python`? Could you be more precise and add an example? — abc, Aug 31 '18 at 02:52
What does *"5,390 when 4**2 is 16"* have to do with this, please edit your question and delete all irrelevant stuff like that. — smci, Aug 31 '18 at 02:55
Can you please clarify your problem? Calculating ``100 * 1.1 ** 7`` in Python gives the correct ``194.87``. The $770 stated in the question is not correct. — MisterMiyagi, Aug 31 '18 at 07:21

In Python, the precedence of the ** operator is more than the * operator. Hence your your statement becomes 100 * (1.1 ** 7) and the answer is 194.87171000000012.

You can refer to https://www.tutorialspoint.com/python/operators_precedence_example.htm for more information on operator precedence in Python.

You can also do this, but the other answer is better code:

i = 0
sum = 100
while i < 7:
   sum = sum * 1.1
   i += i
