Question

In Python Complete the function powersOf5(). Have the function take a parameter n and return a list of the first n powers of 5. One way to calculate powers of 5 is by starting with 1 and then multiplying the previous number by 5.

Examples:

powersOf5( 1 ) returns [1]

powersOf5( 2 ) returns [1, 5]

powersOf5( 3 ) returns [1, 5, 25]

powersOf5( 6 ) returns [1, 5, 25, 125, 625, 3125]

powersOf5( 10 ) returns [1, 5, 25, 125, 625, 3125, 15625, 78125, 390625, 1953125]

Answer 1

code:

output:

def powersOf5(n): #function
powers_of_n_list = [1] #initialize list with one element with value 1, thus index at element 0 is 1
for i in range(1,n): #loop through 1 to n-1
powers_of_n_list.insert(i,powers_of_n_list[i-1]*5) #insert element which is obtained by multiplying 5 with element at previous index at index i of list , thus element at index 1 = element at index 0 * 5 = 1*5 = 5, element at index 2 = element at index 1*5 = 5*5 = 25 and so on..
return powers_of_n_list #return list

print("powersOf5(1): ", powersOf5(1))
print("powersOf5(2): ", powersOf5(2))
print("powersOf5(3): ", powersOf5(3))
print("powersOf5(6): ", powersOf5(6))
print("powersOf5(10): ", powersOf5(10))
