4. Compound Interest Formula Please write Python code to implement the following compound interest formula and solve the problem below. A = P(1 + -)nt n A P = final amount initial principal balance r = interest rate n = number of times interest applied per time period t = number of time periods elapsed 4a) Bank A offers a 5% interest compounded semi-annually (n=2). A customer deposits HKD$1600 on 1st January of a year. At the end of the year, the amount he would have gained by way of interest is: Implement the compound interest formula with the following variables: P = 1680; r = 5/199; n = 2; t=1 Expected output: The interest gained is $81.0 Data Types int integer integer float floating subtraction point multiplication True or False to the power of division // floor division 18 mod bool str [...] list string Math Functions / Conversion abs () input () print () round () type () int() Arithmetic Operators List /String Operations list [...] list[:] Float () str() absolute value 1+ ask user for input display the input value(s) in not in list.sort () list.append() list.pop() remove and return an item at a specific index list.count() count the occurrence of the input item list.index() find the index of the input item len () max() min() sum () round off the input value range (...) return data type of input range (...) convert input to integer convert input to float convert input to string locate item(s) in a list combine two lists/ strings check existence in a list / string check if not exists in a list / string add a new element in the list sort the input list return the number of elements in input list find the biggest element in the input list find the smallest element in the input list find the sum of all elements of the input list create a list of integer Relational Operations is equal? k is less than?
